The gifted rating scales-school form: a validation study based on age, gender, and race.
One important, first step in meeting the needs of the gifted is accurately and efficiently identifying students who might be gifted. At the same time, experts in the gifted field acknowledge that the identification process is fraught fraught

One specific reason for this state of affairs is that, in many school systems across the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America.

Although the IQ test enjoys a long and valued history in gifted identification (Flanagan, Genshaft, & Harrison, 1997; Sattler, 2001 ; Sparrow, Pfeiffer & Newman, 2005), like any psychological test, the IQ test is not infallible in·fal·li·ble

2. and has its limitations. Perhaps the most telling criticism of the IQ test, when used for gifted identification, is the fact that it is rarely used as part of a comprehensive assessment protocol. Many gifted students simply will go unrecognized if the IQ test is the sole measure used for gifted determination (Ford, Harris, Tyson, & Trotman, 2002).
At the present time, few technically sound screening instruments are available to complement the IQ test in providing a comprehensive picture of the student's abilities and potential (gifts). Three of the more popular teacher rating scales designed to identify gifted students are the Scales for Rating the Behavioral Characteristics of Superior Students (SRBCSS; Renzulli et al., 1997 (1)), the Gifted and Talented Evaluation Scales (GATES; Gilliam, Carpenter, & Christensen, 1996), and the Gifted Evaluation Scale, 2nd edition (GES-2; McCarney & Anderson, 1989). Although the SRBCSS, GATES, and GES-2 have positive qualities, they also have technical shortcomings A shortcoming is a character flaw.

Researchers from Duke University recently developed a new gifted rating scale, the Gifted Rating Scales The GRS is a scholastic assessment for school children. It is used mostly for Gifted & Talented admissions. It is administered by a teacher who knows the child well. The teacher rates specific gifted behaviors that they have observed over time.

The GRS was designed to meet an important need in the gifted field: a teacher-completed rating scale that complements the IQ test; is easy to administer and score; technically sound; based on a national standardization sample that matches the latest U.S. census in terms of race/ethnicity, parent education level, and regional representation; and reflects a multi-abilities conceptualization con·cep·tu·al·ize

The GRS test manual reports evidence of reliability and validity. For example, based on the standardization sample, GRS-S coefficient alpha reliabilities ranged from .97 to .99 and standard error of measurements ranged from 1.0 to 1.73 across the six scales and eight age ranges, 6:0-13:11 years.

For example, two studies report high diagnostic efficiency (test sensitivity and specificity) and a lack of bias in terms of race/ethnicity, gender, and age for the standardization sample (Pfeiffer & Jarosewich, 2007; Pfeiffer & Petscher, 2008).
The present study sought to expand upon existing research with the GRS-S, which documents the internal consistency In statistics and research, internal consistency is a measure based on the correlations between different items on the same test (or the same subscale on a larger test). It measures whether several items that propose to measure the same general construct produce similar scores. and validity of the GRS-S standardization sample. The present investigation recruited a new, independent sample to cross-validate findings. The analyses described in this study have not been reported elsewhere. The present study is intended to extend the information reported in the test manual and elsewhere (e.g., Margulies & Floyd, 2004; Ward, 2005).
Subjects consisted of 122 participants from two elementary and middle schools in the southeastern United States. The sample was 60% female (n = 73), 40% male (n = 49), with a mean age of 10.31 (SD = 2.06).

Written authorization was obtained from the university Human Research Subjects Institutional Review Board and the research committee of each participating school district. Principals were contacted in person, informed of the general purpose and procedure of the study, and invited to participate. Assessment packets including parent and teacher informed-consent forms and GRS-S record forms were delivered to each of the schools.
Teachers within the schools who agreed to participate were asked to identify students in their class who performed at one of five levels compared to their peers: (a) students who are performing well above average compared to other students; (b) students who are performing above average compared to other students; (c) students who are average performers compared to other students; (d) students who are performing below average compared to other students; and (e) students who are performing well below average compared to other students.

The Gifted Rating Scales (Pfeiffer & Jarosewich, 2003) includes a preschool/kindergarten form (GRS-P) for ages 4:0 to 6:11 and a school form (GRS-S) for ages 6:0 to 13:11. The GRS-P consists of five scales with 12 items each for a total of 60 items; the GRS-S consists of six scales with 12 items each for a total of 72 items. The items of the GRS-P represent skills and behaviors developmentally appropriate for preschool and kindergarten kindergarten [Ger.,=garden of children], system of preschool education. Friedrich Froebel designed (1837) the kindergarten to provide an educational situation less formal than that of the elementary school but one in which children's creative play instincts would be students, whereas the items of the GRS-S reflect more developmentally advanced skills or behaviors. The GRS-S includes a sixth, leadership scale, which is not included in the GRS-P. Both forms yield raw score totals on all scales, which are converted to age-based T scores and associated cumulative percentages. The present study focuses exclusively on the GRS-S.

1. Intellectual ability. This scale measures the student's verbal and/or nonverbal mental skills, capabilities, or intellectual competence. Items on this scale rate a student's abstract reasoning, problem-solving, mental speed, and memory.
2. Academic ability. This scale measures the student's skill in dealing with factual and/or school-related material. Items rate advanced competence and high levels of proficiency in reading, math, and other aspects of the school curriculum.
3. Creativity. This scale measures the student's ability to think, act, and/or produce unique, original, novel, or innovative thoughts or products. Items rate how a student solves problems, experiments with new ideas, formulates a solution to a group project, and/or uses imagination.
4. Artistic talent. This scale measures the student's potential for, or evidence of ability in, drama, music, dance, drawing, painting, sculpture, singing, playing a musical instrument, and/or acting. Items rate how a student approaches activities, completes assignments, and/or uses art supplies or artistic media.
5. Leadership ability. This scale measures the student's ability to motivate others toward a common or shared goal. Items rate a student's conflict resolution skills, initiative in group situations, and understanding of social dynamics Social dynamics is the study of the ability of a society to react to inner and outer changes and deal with its regulation mechanisms. Social dynamics is a mathematically inspired approach to analyse societies, building upon systems theory and sociology. and interpersonal communication Interpersonal communication is the process of sending and receiving information between two or more people. Types of Interpersonal Communication
This kind of communication is subdivided into dyadic communication, Public speaking, and small-group communication. .
6. Motivation. This scale refers to the student's drive or persistence, desire to succeed, tendency to enjoy challenging tasks, and ability to work well without encouragement or reinforcement. The motivation scale is not viewed as a type of giftedness, but rather as the dynamic energy that drives or impels a student to achieve.
Each item is rated by a teacher on a 9-point scale divided into three ranges: 1-3 (below average), 4-6 (average), and 7-9 (above average). The GRS-S manual provides a classification system that indicates not whether a student is gifted, but rather the likelihood that a student is gifted, based on the T score. The higher the student's T score on one or more of the gifted scales, the higher the probability that he or she is, in fact, gifted compared to same-age peers. The T scores were computed based on each age group and thus age-adjusted so that the classificatory ranges may be applied across age bands. A T score below 55 (below 69th percentile percentile,
n the number in a frequency distribution below which a certain percentage of fees will fall. E.g., the ninetieth percentile is the number that divides the distribution of fees into the lower 90% and the upper 10%, or that fee level ) indicates a low probability of gifted, a score between 55 and 59 (69th-83rd percentile) moderate probability, a score between 60 and 69 (84th-97th percentile) high probability, and a score above 70 (98th+ percentile) a very high probability.
Test development followed a carefully prescribed set of steps, including a survey of gifted experts, focus groups, and pilot and field testing. As mentioned earlier, standardization was colinked with standardization of the new WISC-IV (and WPPSI-III in the case of the GRS-P). Final item selection was guided by factor structure, item mean scores, bias (parent education level, gender, and ethnicity), and interrater and test-retest reliability. For example, an original Intellectual Ability item, asks probing questions, was eliminated from the final version because it loaded on both the Intellectual Ability scale and Creativity scale.
As described earlier, the GRS test manual reports evidence of sufficient internal consistency and validity. The reader interested in more detailed information on the reliability, validity, and normative data is directed to a recent article that reviewed the GRS (Margulies & Floyd, 2004).

in testing (i.e., n < 30), aggregates were created to improve the power of the design and reduce the probability of violating statistical assumptions. To this end, the Asian-, African-, and Hispanic-American subgroups were combined to form a "minority" set that was compared to Caucasian students, increasing the number of minority participants to n = 30. Furthermore, multiple age groups were collapsed, resulting in three categories of age groups: 6- to 8-year-olds (n = 22), 9- to 10-year-olds (n = 44), and 11- to 13-year-olds (n = 54). Although a degree of specificity may be lost by combining subgroups, greater inferences are achieved by keeping the original classes" intact.
The present results indicated very high internal consistency indices for all six GRS scales. Coefficient alpha reliabilities ranged from .98 to .99.

The correlation coefficient is calculated as: among GRS-S scale scores was between Intellectual Ability and Academic Ability (r = .95), with the lowest correlation between Artistic Talent and Leadership (r = .66). These findings were consistent with the internal consistency data reported for the standardization sample (Margulies & Floyd, 2004; Pfeiffer & Jarosewich, 2003; Pfeiffer & Petscher, 2008).

We expected that the GRS-S would not discriminate by gender, race, or age group, signifying Signifyin' (slang) is an African-American rhetorical device featuring indirect communication or persuasion and the creating of new meanings for old words and signs. Signifying, in this sense, includes repetition and difference, implication and association, combining words and that it provided an unbiased assessment of giftedness across important dimensions. The multivariate main effect for gender was not statistically significant, Wilk's lambda = .90, F(6, 103) = 1.96, p > .05, [[eta].sup.2] = .07. Descriptive statistics for each GRS-S scale by gender, race, and age are presented in Tables 2, 3, and 4, respectively. The scale scores for girls and boys were generally equivalent. The largest gender difference was on the Motivation scale (girls M = 58.37 vs. boys M = 51.86); this 6.5-point difference in favor of females indicated moderate practical importance (d = .51). This finding should be interpreted cautiously since the multivariate effect was nonsignificant, indicating that protected testing was not apparent. Other nonsignificant differences by gender ranged between 1.3 points and 3.8 points, all in favor of females. The MANOVA comparing GRS-S scales based on race also did not yield significant results, Wilk's lambda = .97, F(6, 103) = .58,p > .05, [[eta].sup.2] = .03.
Consistent with the results for gender and race, the multivariate main effect for age was not statistically significant, Wilk's lambda = .95, F(12, 206) = .79, p = .02, [[eta].sup.2] = .09. Finally, the MANOVA did not reveal any significant interaction effects for gender by race (Wilk's lambda = .95, F(6, 103) = .97, p > .05, [[eta].sup.2] = .05), gender by age (Wilks lambda = .94, F(12, 206) = .60, p > .05, 1]2 = .03), race by age (Wilk's lambda = .44, F(12, 206) = .85, p > .05, [[eta].sup.2] = .12), or gender by race by age (Wilk's lambda = .96, F(12, 206) = .36, p > .05, [[eta].sup.2] = .02).
We ran two sets of secondary analyses to test whether GRS-S provides an unbiased assessment of giftedness with respect to (a) the length of time that teachers have known the student, and (b) how well they know the student that they are rating. The GRS-S Record Form collects information on these two questions, "How long have you known the child?" and "How well do you think you know the child?" Options for responding to these two questions on the Record Form range between "1-3 months" to "over 1 year" for the first item and "not well" to "very well" for the second item. The multivariate main effects for the length of time, Wilk's lambda = .94, F(18, 295) = .38, p > .05, [[eta].sup.2] = .02, and how well they have known the child, Wilk's lambda = .84, F(12, 208) = 1.58, p > .05, [[eta].sup.2] = .08, were not significant. As expected, the multivariate interaction effect between these two variables, Wilk's lambda = .86, F(18, 295) = .86, p > .05, [[eta].sup.2] = .05, was also not significant. The results indicated that teacher ratings using the GRS-S are not adversely impacted by either how long (or brief) a period of time or how well (or unfamiliar) the teacher might know the student.

The cross-validation study was designed to extend the information reported in the test manual and elsewhere (e.g., Margulies & Floyd, 2004; Pfeiffer & Jarosewich, 2007).
The results of this study are consistent with analyses conducted with the standardization sample. Coefficient alpha reliabilities for the present sample ranged from .98 to .99 for the six scales. Coefficient alpha reliabilities for the standardization sample ranged from .97 to .99 (Pfeiffer & Jarosewich, 2003). The present findings reaffirm re·af·firm

re that the GRS-S scales have excellent internal consistency.
Evidence of validity based on internal structure was examined by exploring intercorrelations among the six GRS-S scales. Intercorrelations were moderate to high, ranging from .66 between Artistic Talent and Leadership to .95 between Intellectual Ability and Academic Ability. Very similar patterns of interscale correlations were found with the standardization sample, ranging from .45 between Artistic Talent and Leadership to .95 between Intellectual Ability and Academic Ability (Pfeiffer & Jarosewich, 2003). The pattern of intercorrelations is consistent with a multidimensional conception of giftedness with an underlying general ability g common factor (Gottfredson, 1997; Jensen, 2004).
Alternatively, the high correlation coefficients among the GRS-S scales may be the result of a halo effect halo effect The beneficial effect of a physician or other health care provider on a Pt during a medical encounter, regardless of the therapy or procedure provided.

put differently , it is possible that the teacher's overall view of the child's ability (g) influences how they view other GRS-S domains. For example, motivation correlated .87 with Intellectual Ability and .89 with Academic Ability. These correlations are unusually high given that there is limited empirical support for high correlations between cognitive abilities and motivation (Gagne & St. Prre, 2001). Conversely con·verse 1

2. , the particularly high correlation between the Intellectual Ability scale and the Academic Ability scale (.95) is consistent with previous findings of very high correlations between measures of ability and measures of academic achievement in the general population (Sattler, 2001; Wechsler, 2003). Item-level factor analysis of the standardization sample found that items on the Intellectual Ability and Academic Ability scales loaded on one principle factor, with all Intellectual Ability items loading consistently about the Academic Ability items (Pfeiffer & Jarosewich, 2003). Many argue that Intellectual Ability and Academic Ability represent a similar if not identical underlying general ability (g) common factor (Carroll, 1993; Flanagan, McGrew, & Ortiz, 2000; Jensen, 2004). With a correlation of .95, these two GRS-S scales have 90% shared variance. Future factor analytic Adj. 1. factor analytic - of or relating to or the product of factor analysis
factor analytical studies employing large samples would provide further insights into the relationship among the GRS-S scales and provide valuable insights into the multidimensional model of giftedness.
It was encouraging that the present cross-validation study did not find any differences for gender, race, or age. This finding provides additional support for the validity of the GRS-S. The gifted field has been concerned, as it should be, with fair and equitable gifted identification practices. There is a history of underrepresentation of African-, Hispanic-, and Native-American students in gifted education Gifted education is a broad term for special practices, procedures and theories used in the education of children who have been identified as gifted or talented. Programs providing such education are sometimes called Gifted and Talented Education (GATE) or programs (Barona & Pfeiffer, 1992; Ford, 1998; Ford & Whiting, 2008; Naglieri & Ford, 2003; Pfeiffer, 2002). When used as either a first-stage screening rating scale or as part of a complete diagnostic battery, the GRS-S holds great promise in identifying any student who has a high or very high likelihood of being gifted.
We ran a set of secondary analyses to examine whether how long a teacher knows the student and/or whether how well a teacher knows the student might influence ratings. Results confirmed that neither length of time in the classroom ("1-3 months," "4-5 months," "7-12 months," or "over 1 year") nor familiarity with the student ("not well," "fairly well," or "very well") biased teacher ratings. This finding may seem counterintuitive coun·ter·in·tu·i·tive
Contrary to what intuition or common sense would indicate: "Scientists made clear what may at first seem counterintuitive, that the capacity to be pleasant toward a fellow creature is ... ; one might suspect that a teacher would feel more confident rating a student after extensive time and familiarity with the student. This issue warrants further exploration. One implication of this finding is that teachers may be able to screen students for gifted identification early in the school year. School psychologists and gifted consultants may not have to wait until well into the school year before asking teachers to complete a GRS-S on one or more students in the classroom. This would make gifted screening early in the school year a real possibility. However, this unanticipated finding merits further investigation before any change in policy regarding early screening is considered by a school district.
The study is not without limitations. The correlations between ratings are not uncorrelated to levels of academic achievement.

The small sample of Asian American (n = 9), African American (n = 17), and Hispanic-Latino (n = 4) students forced us to combine these three groups into one "minority" cohort. If we had obtained a larger sample for our minority groups (n = 30 per group), we would have expected a relatively small effect ([f.sup.2] = 0.06; ([alpha] = 0.05, 1-[beta] = 0.80. Future research would benefit from recruiting a larger sample of students, including a larger group of students from different ethnic/racial groups.
