The examination for teachers at the elementary level consists of only two parts: the general education and the professional education; while the examination for the secondary level consists of three parts: the general education, professional education, and field of specialization. General education refers to core subjects like Filipino, English, Math, Science, and Social Science/Studies. Professional education refers to those related to the teaching profession like Facilitating Learning, Early Childhood and Adolescent Development and Education, Principles of Teaching, Methods and Strategies, Curriculum Development, and the Teaching Profession as a whole. Lastly the field of specialization refers to the specific discipline the secondary teachers have to teach like English, Biology, Chemistry, Math, Filipino, Social Studies, Music, Art, Physical Education and Health or MAPEH. 

The LET was implemented in the Philippines throught the enactment of Republic Act 7836 or otherwise known as the “Philippine Teachers Professionalization Act of 1994” on December 16, 1994. The enactment of the law didn’t mean that the teachers in the Philippines were not “professional”. Rather it is a means to strengthen and improve not just the teachers, but also the quality of education and the whole education system in general. By improving the teachers, the students will naturally follow the embetterment of those who lead them.                Before R.A. 7836 was implemented, education in the Philippines was mostly regulated and supervised by the National Board for Teachers (NBT). Even though R.A. 7836 was signed as law in 1994, the first LET exam was held two years later. On August 1996, a total of 97,560 examinees took the first LET exam administered by both the Board for Professional Teachers (BPT) and the Professional Regulation Commission (PRC).
