Having K-12 implemented in the Philippines is actually not a bad idea. If you'll read DepEd's discussion paper on this matter, they've relayed a lot of good points on why K-12 should be implemented. However, you have to consider a few things: lack of facilities, trained and capable teachers, families' capability of sending their child/ren to school and the poor financial status of the country. So I think K-12 is possible but not feasible today.
