Dinas Powys technically has no secondary school of its own but was home to one half of Penarth’s St Cyres Comprehensive School.
The "Dinas Site" was the smaller of the two existing facilities and contained the locally living lower school students from year seven to year nine, representing ages 11 to 14, while upper school for the older children is located on Redlands Heights in Penarth.
However, the St Cyres lower school in the village closed in 2012, and was replaced by a larger single redeveloped site located in Penarth.

The village also has two other schools - Dinas Powys Primary School (Formed in 2015 by the amalgamation of the Dinas Powys Infants school and the Murch Junior School) and St Andrews Major Church in Wales Primary school.
