In the Philippines, the Department of Education mandates that elementary school lasts for 6 years in the public school system starting with grade 1 and culminating with grade 6. After successful completion of the 6-year programme shall a student graduate, be awarded an elementary diploma and can move-on to a 4-year high school programme (most private schools will require an entrance examination). However most private schools (who usually call the elementary level as grade school), especially exclusive schools and those accredited to have a high degree of autonomy from the Department of Education usually extend their programmes to 7th grade and can also include levels such as nursery, kindergarten or preparatory (prep) as entry levels prior to 1st grade. Subjects usually taken-up include Communication Arts in English (some private schools break this down into Language and Reading) and Filipino, Mathematics, Science, Social Studies (taught in Filipino), Home Economics (HELE - for all-girls schools), Music, Art and Physical Education (which in some schools is collectively known as MAPE). Students in the 6th grade, whether studying in a public or private school are required to undergo a National (Elementary) Achievement Test (NAT) even if grade 6 isn't the terminal level in that school. The NAT is similar to certain schemes like Primary School Leaving Examination of Singapore (PSLE) except that that NAT score isn't used as a basis to admit students to a high school.
