Education(al) supplement

[Nonverbis]

This is Upstream Proficiency by Virginia Evans and Jenny Dooley.

Could you tell me whether it is education supplement or educational supplement.

 

[jutfrank]

It should be education supplement as it's a supplement to do with the world of education. It isn't educational in itself.

Thank you. Sounds strange for me. I was more inclined to educational.
