School Notes

  • Mercy is a two-time recipient of the National Blue Ribbon School of Excellence award, and consistently meets the qualifying criteria with student achievement placing in the top 15th percent nationally.  Re-accredited by The Commission on Elementary Schools of the Middle States Association of Colleges and Schools in 2008, Mercy was commended for its outstanding Educational Excellence Program. We provide a rigorous academic program that engages and challenges students at all levels, while recognizing and responding to individual needs.  Every Mercy student receives small group instruction for both math and language arts. Teachers are able to provide personalized support and enrichment, to delve deeper into the curriculum, and to make real-world connections, all of which promote student engagement, interest, and growth.

Mercy is a wonderful place to learn. I love the sense of community that was missing in our neighborhood public school. The students have "prayer partners", which builds a strong bond between the older and younger students. The school has great opportunities for service to the community. The teachers are extremely kind and supportive. My older child is learning wonderful organizational skills as she is being prepped for middle school. While the educational style is more on the traditional side, there is an emphasis on the basics; handwriting, written composition and grammar that are lacking in the public school curriculum. Mercy is the full package, community and strong academics.

We could not be happier with Mercy. The faculty is amazingly dedicated. There is a top notch special education/"inclusion program". My kids are not in the program but it is actually a benefit for the entire school. Mercy has proven to be a nurturing, challenging and inclusive environment where all children are accepted and truly seem to thrive. We could not be happier. In this area it is also a bargain!! Love it!!!
