The Gifted Rating Scales Second Edition (GRS™ 2) is a revision of the well-established Gifted Rating Scales (GRS). The GRS™ 2 incorporates many of the benefits of the original GRS but was carefully designed to offer enhanced functionality and accessibility. New features include:

• An expanded age range (4–18 years).
• Teacher Form updates with item revisions, a reduced number of items per scale, and updated norms.
• A new Parent Form gives users additional data points for Cognitive Ability, Creative/Artistic Ability, and Resiliency & Social Competency in the assessment process for gifted identification. The Parent Form enables ratings based on behaviours observed in different contexts, allowing for a more holistic view of students’ abilities.
• A new modular administration with the option to select which scales to administer.
• New modular reports with rater response-style indicators.
• Analyses of students’ relative strengths.

All GRS™ 2 users receive access to a free, digital version of the GRS™ 2 Manual through their MHS Online Assessment Center+ (MAC+) account.

Key Areas Measured

reports

Online scoring  can generate two types of GRS 2 reports:

  1. Single-Rater Report—provides one student’s scored results from one rater. 
  2. Scored Dataset—provides all students’ scores within a single spreadsheet.

Reliability

The GRS™ 2 Teacher–Preschool/Kindergarten Form (GRS 2 Teacher–P), GRS 2 Teacher–School Form (GRS 2 Teacher–S), and GRS 2 Parent Form (GRS 2 Parent)  showed evidence of reliability through high internal consistency coefficients (e.g., median omega across age groups, raters, and scales within the Normative Samples: GRS 2 Teacher–P = .98, GRS 2 Teacher–S = .98, and GRS 2 Parent = .91); a high degree of test information, providing evidence for the precision of measurement; statistically significant (p < .001), strong to very strong, and positive test-retest correlation coefficients between scores across a 2- to 4-week interval (GRS 2 Teacher–P: corrected r = .66 to .80; GRS 2 Teacher–S: corrected r = .74 to .91, GRS 2 Parent: corrected r = .62 to .74);  and statistically significant (p < .001) and strong inter-rater reliability between school-age teacher raters (corrected r = .65 to .76), and between parent raters (corrected r = .71 to .76).
 

Validity

The GRS™ 2 showed evidence of  validity through confirmatory factor analyses (CFA) that provided evidence to support the structure of the GRS 2 scales (final models had strong fit statistics for all forms [CFI and TLI ≥ .923; SRMR ≤ .047; RMSEA ≤ .069] and replicated the structure of the original GRS™); meaningful differences between the General Population and the Gifted Samples, such that gifted students yielded higher scores than students from the general population (median Cohen’s d = 0.90 across all forms and scales), providing evidence of criterion-related validity; and evidence of convergent validity through strong associations between the Resiliency & Social Competency scale from the GRS 2 Parent and the Social Skills and Resiliency scales from the Behavior Assessment System for Children, Third Edition (BASC–3; Reynolds & Kamphaus, 2015; corrected r = .68 for both scales).
 

Fairness

Evidence of fairness was established through  the absence of meaningful psychometric differences between demographic groups. There was no evidence of measurement bias due to the gender (maximum |ETSSD| = 0.07), race/ethnicity (maximum ETSSD = |0.07|), primary language spoken (maximum ETSSD = |0.27|), parental education level (PEL; maximum ETSSD = |0.04|), household income (maximum ETSSD = |0.06|), or country of residence (maximum ETSSD = |0.13|) of the student being rated.
