Primary Test of Cognitive Skills (PTCS) is a group-administered series of tests that provides a reliable, valid indication of young learners' cognitive abilities. Four untimed sub-tests assess verbal, spatial, memory, and concepts skills. Based on careful research, PTCS helps teachers identify young students who may be gifted, have learning disabilities, or have unique developmental delays.

PTCS was standardized on a 2007 norm group. When used with TerraNova, Third Edition, PTCS provides anticipated-achievement scores for individual students and groups, allowing you to compare your students' achievement with that of other students of the same age, grade, and ability—and determine whether your students are achieving to their full potential.
