Oldest high school in the Philippines?

The title of "oldest high school in the Philippines" is a bit complicated, as it depends on how you define "high school" and what records are considered. There's no single universally accepted answer.

However, strong contenders for the oldest include schools that were established during the Spanish colonial era and evolved into what we now recognize as high schools. These would likely be among the oldest *secondary* schools, even if they didn't initially have the exact structure of a modern high school. Precise founding dates can also be debated.

Therefore, there's no definitive answer readily available online. Further research into the historical records of various old secondary schools in the Philippines would be necessary to make a conclusive determination.
