The SAGES-3 helps identify gifted students in grades K–8. The SAGES-3 offers many exciting benefits, including:

  • new national norms that conform to the 2017 census;
  • easy group administration by school personnel;
  • stand-alone subtests for Language Arts & Social Studies, Math & Science, Verbal Reasoning, and Nonverbal Reasoning; and
  • easy, fast scoring procedures.

General Description. The SAGES-3 measures both aptitude and achievement. Aptitude is measured via the reasoning subtests, in which the child is asked to solve problems by identifying the relationships between pairs of words (verbal) and the relationships among figures and pictures (nonverbal). The other two subtests assess achievement. On one, the child answers questions about language arts and social studies; on the other, mathematics and science. The subtests can be used to examine the relationships between aptitude and achievement. Each subtest requires 15–30 minutes to administer. All of the SAGES-3 subtests can be administered in small groups or individually and are scored by school professionals.

Technical Description. The SAGES-3 was normed on data collected from 2015–2017. The normative sample consisted of 1,834 students. The demographic characteristics of the sample matched to those of the United States according to the 2017 census. The normative sample was stratified on the basis of age, gender, race, ethnicity, household income, geographic location, and educational attainment of parents.

All-new reliability and validity studies were prepared, including diagnostic accuracy analyses, which are considered the most rigorous techniques for establishing validity today. The average coefficient alpha ranges between .81 and .96 for the subtests and from .91 to .98 for the composites. The new validity studies demonstrate the test’s ability to differentiate students with high IQs (130 or higher) from students with lower IQs (below 130).

New and extensive studies of test bias (both differential item functioning and subgroup comparison studies) were conducted, indicating that the SAGES-3 possesses little or no bias in regard to gender, race, or ethnicity. Additional studies of construct-identification validity were also provided. These studies indicate that the SAGES-3’s internal structure is sound and its results are valid.
