The National Achievement Test Reviewer refers to the study materials that prepare Filipino students for a test administered by the Department of Education in the Philippines. These materials include study guides and a mock exam. Each year, the National Achievement Test, or NAT, is administered during the first week of March by the National Educational Testing and Research Center.
The NAT covers the subjects of mathematics, science, English and Filipino as well as HeKaSi in elementary and Araling Panlipunan in high school. The NAT includes multiple choice questions in analysis, vocabulary, reading comprehension, problem solving and general knowledge. It also includes composition writing and critical thinking essay portions. The NAT is given to 4th, 6th and 12th graders to determine their academic strengths and weaknesses. The NAT covers material learned over the course of several school years, but each school hosts a week-long review before the exams. The NAT has a time limit of 4 to 6 hours, depending on the grade. There are between 205 to 325 questions on the NAT. The ratings acquired by the NAT are also used to measure each school's competency and effectiveness. The Filipino Department of Education urges students not to miss school on NAT review days.
