The National Physical Fitness Award (NAPFA) is a standard physical fitness test for Singaporeans as part of Singapore's Sports For Life programme. NAPFA was launched in January 1982 as a standardised assessment of overall fitness for the general population. All primary and secondary schools in Singapore are required to participate in NAPFA tests on alternate years, in April for secondary schools and in August for primary schools respectively. It is one of the three criteria for banding for the Trim and Fit (TAF) Awards, other than the fitness index and the percentage of overweight students. Singaporeans studying within Singapore's tertiary education system, or those who have graduated from the education system are not required to participate, but are strongly encouraged to do so. Despite the requirement for mandatory participation, failing to achieve at least a passing grade (E) usually does not carry any academic consequences for primary and secondary school students, although students are still strongly encouraged to pass. Exceptions include sports-based schools such as the Singapore Sports School, and might yield non-academic consequences, such as the requirement to further retake the tests or the required participation in the Trim and Fit programme. Before the changes to the IPPT, a minimum of a silver grade allowed Singaporean males who have reached the age of 18 to perform just 9 weeks of Basic Military Training (BMT) in their National Service (NS) period, instead of the usual 17 weeks if the silver grade is not attained. Those without at least a NAPFA Silver have to undergo an extra eight-week Physical Training Phase (PTP) prior to their nine-week BMT. In addition, medically fit servicemen who have attained a silver grade enjoy a two-month exemption at the end of their full-time NS period because exemption from PTP would mean a reduction of two months of NS, making the entire NS shortened to one year and ten months. With the new IPPT system, the exemption criteria for PTP is now 61 points based on sit-up, push-up and 2.4 km run done in a single session, graded according to the IPPT scoring system. According to data from the Ministry of Education, the percentage of students passing NAPFA has been increasing steadily over the years, from 58% in 1992 to 74% in 1998, and further to 80% in 2007. Testing NAPFA involves a series of five stations and a 2.4-km (1.5-mile) Walk-Run for secondary school students and
