Tin Keo Primary School was built by villagers of Tin Keo and started operating in early 2009, with 18 children attending from the village.

Today, 36 students attend the Tin Keo school which has been supported by Grand Circle Foundation since 2012. The classroom is divided into two grades but there is only one teacher. Grand Circle Foundation provided funding to install electricity; add ceiling fans; paint the inside and exterior of the school; build toilets; provide a playground; and add a library room.
