Lesson 2 discussed how education systems around the world generally require basic compulsory education, though the number of years required varies by country. In the Philippines, kindergarten is now mandatory under Republic Act 10157. Students receive a diploma or certificate upon completing each level of basic education, such as grade 6, 10, or 12, which is required to advance to higher education available in most countries. With the K-12 program, the Philippines now has the same number of years in basic education as other countries. Advanced higher education such as master's and doctoral degrees can be obtained in many colleges and universities both in one's home country and abroad.
