The School and College Ability Test (also sometimes called the Scholastic and College Ability Test or SCAT) is used by John Hopkins University Center for Talented Youth (CTY) as part of their admissions process.
John Hopkins uses the SCAT for above level assessment.
There are three versions of the School and College Ability Test currently in use:
Students in Gr 2-3 take the Elementary SCAT designed for students in Gr 3-6
Students in Gr 4-5 take the Intermediate SCAT designed for students in Gr 6-9
Students in Gr 6-8 take the Advanced SCAT designed for students in Gr 9-12.
