The document discusses several standardized tests administered to students: the CogAT, Iowa Test, and CRCT. The CogAT and Iowa are norm-referenced tests that measure cognitive abilities and academic achievement compared to national samples. The CRCT is Georgia's criterion-referenced test that measures mastery of state standards. Test scores are used to guide instruction, identify gifted students, determine student needs, monitor growth, and evaluate programs. The document provides information on scoring and how results from these assessments inform teaching and learning.
