The SAGES-2 helps identify gifted students in kindergarten through eighth grade. A complete revision of the acclaimed SAGES and SAGES-P, the SAGES-2 offers many new and exciting benefits, including:
  • easy, group administration by school personnel;
  • stand-alone subtests for language arts and social studies, math and science, and nonverbal reasoning; and
  • easy, fast scoring procedures
This test may be administered to groups of students and scored by school professionals. Student results are presented in an easily understandable manner for communication with parents.

General Description The SAGES-2 measures both aptitude and achievement. Aptitude is measured via the reasoning subtest. The child is asked to solve analogical problems by identifying relationships among pictures and figures. The other two subtests assess achievement. On one of these subtests, the child answers questions about language arts and social studies; on the other, he or she answers questions about mathematics and science. The child selects answers from a series of pictures, symbols, or words. The subtests can be used to examine the relationships between aptitude and achievement. While untimed, each subtest requires approximately 20 minutes to administer. All of the SAGES-2 subtests can be administered in small groups or individually.

Technical Description The SAGES-2 was normed on two large samples tested in 1998 and 1999. Sample 1 (normal sample) consisted of 3,023 students who were in heterogeneous classrooms, and Sample 2 (gifted sample) consisted of 2,290 students who were identified as gifted by their local school districts. The demographic characteristics of both samples were matched to those of the United States according to the 1997 census. The normal normative sample was stratified on the basis of age, gender, race, ethnic group membership, and geographic location. Standard scores and percentile ranks are provided for other samples.

Several important improvements to the technical characteristics of the SAGES were made. First, test/retest studies were added. Second, each item on the test was evaluated using both classical item analyses and item-response theory to choose "good" statistical items. Third, differential item functioning analyses were performed on three dichotomous groups in order to find and eliminate adversely biased items. Finally, several new validity studies were conducted with special attention devoted to showing that the test is valid for a wide variety of subgroups, as well as for a general population.

The reliability coefficients for the test are high, ranging from .77 to .95. Ninety-seven percent of these reach or exceed .80, and 74% reach or exceed .90. Test/retest studies show that the SAGES-2 is stable over time. The potential bias of every item on the test on the basis of gender and ethnic group was studied. In all, 44 items were eliminated from the final version.

Exhaustive validity data are reported, as well, documenting the test's relationship to the WISC-III, OLSAT, Stanford Achievement Test, and Gifted and Talented Evaluation Scale and its efficiency in discriminating groups appropriately.
