3/10GreatSchools RatingParent Rating AverageI HATE THIS SCHOOL!!!! I am deeply disgusted with the School District for the way they handled replacing the Principal. They gave NO WARNING to the fanilies, students - NO ONE!! The Superintendent, Dr. Jones should be ashamed of herself for mishandling the children of Medford Elementary. I contacted the Commissioner in Albany over this.Parent Review6y ago - Patchogue Medford High School

5/10GreatSchools RatingParent Rating AverageBoth my kids graduated from Patchogue Medford and were on honor roll quarter after quarter. Now, both are in college getting good grades. Patchogue Medford was a good experience for both my kids. No issues and in particular, guidance was excellent as were many of the teachers. Thank you Patchogue Medford.Parent Review2y ago - South Ocean Middle School

6/10GreatSchools RatingParent Rating AverageThis school is highly underrated. They might not put as much focus on state tests as other schools but instead make sure your child learns material that will benefit him/her in High School. They focus on your child as a whole and provide ample opportunity for academic growth. The student body is diverse in a healthy way. Children learn to engage with peers from different backgrounds instead of growing up in ethnocentric and classist bubbles.Parent Review9y ago
