K-12 Education System
It can enhance education but there are more disadvantages than advantages.
One disadvantage, one more year in school means more expenses for our parents and the common reason of the youth not finishing school is the lack of budget.
Another is the lack of jobs, they are saying that it would be easier for us if K12 will be applied because after high school you can already get a job but the problem is there are no jobs and if ever there is, there would be a very small chance of a high school applying being hired because there are also college graduates applying. You can't say that high school graduates are the only ones can apply in this articular job because there are really a lot of college graduates unemployed and it would be really unfair.
And also, the school facilities. A lot of school don't have complete facilities and lacking of rooms. Imagine a 70:1 ratio in most of the schools here.
There are more things to be straighten out before K12 can really be used.
