 Its successors, the National Career Assessment Examination (NCAE) and National Achievement Test (NAT) were administered to third- and fourth-year students respectively, before the implementation of the K-12 system.The National Career Assessment Examination (NCAE) is now being administered for Grade 9 and the National Achievement Test (NAT) is being administered at Grade 6, 10, and 12.Neither the NSAT nor NAT have been used as a basis for being offered admission to higher education institutions, partly because pupils sit them at almost the end of their secondary education.
