We were at EL Haynes for prek3 - k and enjoyed it a lot. I would put it academically on par with a high-performing title I DCPS school, with better aftercare and much better arts/music. There was a lot of academic emphasis in pre-K, e.g. major focus on literacy. It was almost too much for me to be honest, I thought there was too much “work” and not that much play. The teachers are generally pretty good, we had an excellent pre-K4 teacher who was probably one of the best teachers my children have ever had. But all the teachers were good.
The art instruction was fantastic, and there was music and dance. That was wonderful.
We left when we moved west of the park. We had never intended to stay past kindergarten, so I never really investigated the upper grades.
Anecdotally, I think the vibe really changes in middle school. The middle school campus is on Jorge Avenue, and they almost doubled the class sizes.
