I have to echo the sentiments of the previous parent. I too was new to the area and heard many negative things about WP. My daughter in graduating this year and has had a very positive experience at WP. The school has a very good acdemic program. The Teachers and Staff are very responsive and the facility is well maintained inside and out. This school rivals any of the charter schools in the area. I think we need to support our public schools and the teachers and staff there. They do a wonderful job.
New the area 7 years ago, many neighbors told me how 'bad' it is at WP. We decided to see for ourselves, and we're glad we did. The staff and faculty are very responsive and helpful. My children both did very well academically and socially. Both were (are) involved in both the music program and sports. The facilities are a matter of pride. You will not find a dirty bathroom, hallway, or classroom at Penn. Coaches, teachers, administrators should all be recognized for all they do at William Penn.
