The Gifted Rating Scale (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. [1]
Rating scales have developed since the early 1970s to assess general child psychometrics and psychopathology.
The Gifted Rating Scales, first published in 2003, are authored by Steven Ira Pfeiffer (1950-), and Tania Jarosewich. The GRS is completed through teacher evaluations and measures giftedness on multiple scales.
The GRS-P, designed for children in preschool and kindergarten, evaluates children on five scales:
The GRS-S, designed for children in grades 1–8, evaluates giftedness in children on six scales:
Notwithstanding skepticism — that laypeople lack expertise, objectivity, and consistency to administer the GRS — Harbrace contends that the GRS, by design, allows for minimal observational bias and a high degree of measurement accuracy, especially at higher levels.
One of the best advantages of using the GRS, as compared to interviews, is that it is easy to administer and less expensive than traditional large-scale testing. Time for administration is usually modest. Rater bias and subjectivity of responding can be reduced by using a standardized presentation of questions, though this has yet to be researched. The GRS can be routinely administered in schools. While the GRS itself is fairly new, rating scales tend to have good data on reliability and validity.
GRS validation studies have been accepted for publication in journals including Gifted Child Quarterly, which has accepted three GRS validity studies, the Journal of Psychoeducational Assessment and the Roeper Review. It is important to note that research on the topic of the GRS has been published by the authors of the GRS, or one of their current or former students. Interested persons should consult the Buros Mental Measurement Yearbook review of the GRS for additional information on this and other rating scales.
Harcourt Assessment, Inc. is a unit of Harcourt Education, which is part of Reed Elsevier Group plc.
The GRS as a rating scale has yet to be evaluated up to the level commonly accepted by major research associations (NCTM, AERA, APA). As such its use in gifted and talented identification at this point is questionable. Although the GRS is among the top-tier of such rating scales meant to be used for gifted and talented identification, it is also by far the most expensive.
The GRS assessment is controversial because, among other things, intellectually gifted children at the highest levels are often not "teacher pleasers" and can be misunderstood or evaluated with prejudice, especially by laypeople with no expertise in giftedness. Moreover, raters can't access, guess, or factor for certain likable or unlikable characteristics such as hyperactivity or inattention or aggressive/stubbornness.
Rating scales, in general, can be subject to rater bias based upon the characteristics of the rater. This is of particular concern for children being evaluated for kindergarten because the credentials of the raters from preschools greatly vary. Slight changes in the wording of instructions, or the wording of the items themselves, may have a significant effect on the child's response.
Data obtained from ratings rely totally on the rater's familiarity with the child. In practice, the rater of a preschooler, for example, may not be the same person that spends time with the child.
Rating scales, in general, are limited to the informant's perspective. Information that may be relevant to the subject, but that is not covered by the items of the scale will be missed. With rating scales, it is not possible to explore the informant's responses and subjective experiences, nor is it possible to observe behavior directly.
Because the GRS is administered by laypeople, critics aver that in a large school system, such as New York City, problems with measurement consistency can be tolerably contained within Regions; but it can be injurious to students wrongly admitted to more rigorous citywide schools for intellectually gifted.
In the case of the New York City public schools, the implementation of the GRS and the OLSAT, together, essentially represent a shift away from using IQ as the prime criteria for identifying special needs. It also removes the assessment duties from the erstwhile used tightly controlled NYC DOE process that uses pre-approved, independent child psychologists (who had, until 2007, administered the Stanford Binet), and gives most of the duties, instead, to a publishing company and laypeople. [2]
IQ in the top 5% is difficult to accurately measure. The GRS is too new to have been adequately normed for acceptable accuracy at those levels.
Criteria, such as Leadership and Motivation, are often counter-correlated with high IQ, so the GRS might actually screen out children who most need special attention.

An intelligence quotient (IQ) is a total score derived from a set of standardised tests or subtests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
Psychological testing refers to the administration of psychological tests. Psychological tests are administered or scored by trained evaluators. A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. The science behind psychological testing is psychometrics.
The Stanford–Binet Intelligence Scales is an individually administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Théodore Simon. It is in its fifth edition (SB5), which was released in 2003.
Intellectual giftedness is an intellectual ability significantly higher than average. It is a characteristic of children, variously defined, that motivates differences in school programming. It is thought to persist as a trait into adult life, with various consequences studied in longitudinal studies of giftedness over the last century. There is no generally agreed definition of giftedness for either children or adults, but most school placement decisions and most longitudinal studies over the course of individual lives have followed people with IQs in the top 2.5 percent of the population—that is, IQs above 130. Definitions of giftedness also vary across cultures.
Gifted education is a sort of education used for children who have been identified as gifted and talented.
Educational assessment or educational evaluation is the systematic process of documenting and using empirical data on the knowledge, skill, attitudes, aptitude and beliefs to refine programs and improve student learning. Assessment data can be obtained from directly examining student work to assess the achievement of learning outcomes or can be based on data from which one can make inferences about learning. Assessment is often used interchangeably with test, but not limited to tests. Assessment can focus on the individual learner, the learning community, a course, an academic program, the institution, or the educational system as a whole. The word "assessment" came into use in an educational context after the Second World War.
When children are young, schools begin to analyze the youngsters’ abilities and sort them into clusters based on their predicted success. The system labels the cream of the crop as gifted. Clark (2002) defines giftedness as “only a label that society gives to those who have actualized their ability to an unusually high degree or give evidence that such achievement is imminent”. The American government defines giftedness as “students, children or youth who give evidence of high performance capability in areas such as intellectual, creative, artistic, or leadership capacity, or in specific academic fields, and who require services or activities not ordinarily provided by the school in order to fully develop such capabilities”. Gifted students learn in a different manner and at an accelerated rate compared to their peers in the classroom and therefore require gifted programs to develop and apply their talents.
Cognitive tests are assessments of the cognitive capabilities of humans and other animals. Tests administered to humans include various forms of IQ tests; those administered to animals include the mirror test and the T maze test. Such testing is used in psychology and psychometrics, as well as other fields studying human and animal intelligence.
The Highly Gifted Magnet (HGM) is part of the Los Angeles Unified School District's Gifted and Talented program, designed for students of extraordinary intelligence who have unique intellectual, social and emotional abilities not nurtured by normal Gifted programs. The purpose is to cluster students of similar capabilities and needs with teachers who can challenge them with greater academic and intellectual rigor while meeting their social and emotional needs. These relatively small programs are housed on larger campuses. In a Los Angeles Times review that separated Magnet test scores from their host schools, HGMs consistently had the highest standardized test scores of all LAUSD schools.
The Wechsler Intelligence Scale for Children (WISC) is an individually administered intelligence test for children between the ages of 6 and 16. The Fifth Edition is the most recent version.
Julian Cecil Stanley was an American psychologist. He was an advocate of accelerated education for academically gifted children. He founded the Johns Hopkins University Center for Talented Youth (CTY), as well as a related research project, the Study of Mathematically Precocious Youth (SMPY), whose work has, since 1980, been supplemented by the Julian C. Stanley Study of Exceptional Talent (SET), which provides academic assistance to gifted children. Stanley was also widely known for his classic book, coauthored with Donald Campbell, on the design of educational and psychological research - Experimental and Quasi-experimental Designs for Research.
The Differential Ability Scales (DAS) is a nationally normed, and individually administered battery of cognitive and achievement tests. Into its second edition (DAS-II), the test can be administered to children ages 2 years 6 months to 17 years 11 months across a range of developmental levels.
The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is an intelligence test designed for children ages 2 years 6 months to 7 years 7 months developed by David Wechsler in 1967. It is a descendant of the earlier Wechsler Adult Intelligence Scale and the Wechsler Intelligence Scale for Children tests. Since its original publication the WPPSI has been revised three times in 1989, 2002, and 2012. The latest version, WPPSI–IV, published by Pearson Education, is a revision of the WPPSI-R and the WPPSI-III. It provides subtest and composite scores that represent intellectual functioning in verbal and performance cognitive domains, as well as providing a composite score that represents a child’s general intellectual ability.
The Draw-a-Person test is a psychological projective personality or cognitive test in which the test subject uses simple art supplies to produce depictions of people. It is used to evaluate children and adolescents for a variety of purposes.
The Otis–Lennon School Ability Test (OLSAT), published by the successor of Harcourt Assessment—Pearson Education, Inc., a subsidiary of Pearson PLC—is, according to the publisher, a test of abstract thinking and reasoning ability of children pre-K to 18. The Otis-Lennon is group-administered, multiple choice, taken with pencil and paper, measures verbal, quantitative, and spatial reasoning ability. The test yields verbal and nonverbal scores, from which a total score is derived, called a School Ability Index (SAI). The SAI is a normalized standard score with a mean of 100 and a standard deviation of 16. With the exception of pre-K, the test is administered in groups.
IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient (IQ) tests, into categories such as "superior" or "average".
The Naglieri Nonverbal Ability Test (NNAT) is a nonverbal measure of general ability designed by Jack A. Naglieri and published by Pearson Education. The Naglieri Nonverbal Ability Test - Individual Form was first published in 1998. Two versions were published in 2007 and 2008, respectively. This includes the group administered Naglieri Nonverbal Ability Test - Second Edition and the Naglieri Nonverbal Ability Test - Online version. The most current version is NNAT3. Like all nonverbal ability tests, the NNAT is intended to assess cognitive ability independently of linguistic and cultural background.
The Woodcock–Johnson Tests of Cognitive Abilities is a set of intelligence tests first developed in 1977 by Richard Woodcock and Mary E. Bonner Johnson. It was revised in 1989, again in 2001, and most recently in 2014; this last version is commonly referred to as the WJ IV. They may be administered to children from age two right up to the oldest adults. The previous edition WJ III was praised for covering "a wide variety of cognitive skills".
TestingMom.com is an online test prep for parents of gifted education and testing along with skill building, founded in 2010. Testing Mom membership services include expert advice, tele-seminars, practice questions, as well as books and games. The online programs help parents of children pre-K to 8th grade with skill building activities for school success and testing success. The platform also has content for common core testing and state testing.
The Gesell Developmental Schedules are a set of developmental metrics which outline the ages & stages of development in young children developed by Dr. Arnold Gesell and colleagues. The original scale is generally considered not to satisfy the standards of rigor currently accepted in the field of psychometrics and is no longer used as an evaluative rubric in the clinical context. The most current form of the schedules comes from the Gesell Institute of Child Development and is known as the Gesell Developmental Observation-Revised for ages 2 ½ to 9 years. This assessment uses the principles of the schedules to determine the developmental age & stage of an any given child.
