The EFA (Education for All) is a global initiative which aims to provide education needs for all children, youth and adults by 2015. Being a signatory in this global pact, it is incumbent upon the Philippine government to make education accessible not only to the majority of the Filipino people but to ALL Filipinos.
Having said this, it is my view that your situation does not fall within the scope of EFA because: (a) Fulfillment of the EFA duties lies with the government of the Philippines through the creation of agencies or bodies as well as the adoption of policies and measures designed to ensure that the EFA goals are attained; and (b) There is no enabling law based on EFA prohibiting teachers from rejecting students for valid cause.
In any case, I suggest that you give due consideration to your students. They may have their respective valid or compelling reasons for their failure to appear during the first and second grading period. Why not give them a chance to be in your class and allow them to take the upcoming examination/s. If they passed the exam, they have established their worth to become part of the graduating class. If they fail, it is always your prerogative as teacher to fail students who do not pass the exam.
