My children attended Mt. Calvary and were beyond prepared for their high school experiences. Mt. Calvary prepared them in writing, math, critical thinking and motivation. I cannot praise this school enough. They also learned the importance of faith and confidence.

We decided to have our kids attend Mt. Calvary 7 years ago and have been there ever since. It was the best decision we've ever made! The kids LOVE the school so much that they look forward to going each morning. We love the family first environment. The academic & Christian education is top notch. These students can compete against any in the nation. The staff cares about the students so much it is heartwarming. Plus the new Principal is very proactive at doing everything he can to improve the school even though at this time I can't think of anything it needs to improve on. We HIGHLY recommend this school.

My daugher and son have been attending Mt. Calvary since pre-school. My main focus was to bring them up in a good Christian School with strong academics. Everything that I`d hoped for them to have is exactly what they get. Wonderful "Christ-Centered" academics that have continued to astound my husband and I. When we see where they are academically compared to friends and family in the same grade it blows us away. The teachers put in so much of their time with these kids to make sure they are getting the most out their learning. We love the smaller class sizes, so that our children have more of a persolized education. We are extremely grateful and happy to have Mt. Calvary and these special teachers in our lives.

Both our kids were positioned for success after graduating from Mt Calvary. They were well prepared for high school socially and academically. Mt Calvary uses rigorous educational standards and spiritual grounding to help parents raise strong, independent kids, ready for life's challenges!

Our daughter began at Mt. Calvary Lutheran in Diamond Bar as a preschooler. We were referred by close friends whose children had graduated and gone on to be high school valedictorians. From the moment we were greeted for the introductory tour we knew our daughter was going to be in the right place. She is now a second grader and has blossomed into a little girl that is confident in her faith, academics, and social skills. If you can imagine tenured teachers that have been teaching at this school for years with class sizes that average 15 students then you've imagined Mt. Calvary. I look forward to the future and what it holds in respect to my daughter's ongoing education at this school.

My four year old son is finishing his first year at Mt Calvary's preschool. We had him go twice a week / half day. I'm amazed at what he has learned in that short amount of time. I would definitely say it is not baby sitting. He is being taught kindergarten curriculum in math and writing. I see him more advanced going into kinder then his sibling did two years ago (went to a different preschool). I've also been impressed with their constant teaching of the bible and how it's integrated in daily lessons. My son has grown academically as well as spiritually. As a result, we've decided to enroll both our kids into their k-8 program next year.Update: Kids are loving their school and friends! I would say I have found the curriculum to be much more advanced then at the public school. My second grader has had to catch up a bit, but is doing really well. I love the staff and families that attend. Everyone is so happy and friendly. It's really a "community" feeling. I also like the enrichment programs they offer afterschool; my kids are taking piano right after school!

We love Mt Calvary Lutheran School. The academic program is impressive. The staff and administration provide a pro-gram that is seamless and focused. Learning is taught in an environment that promotes critical thinking across the educational spectrum. My children are taught Christian character values, self reliance, accountability, time management skills, and research skills in addition to the academic program. The skills my Daughters learn at Mt Calvary were immediately recognized by their high school teachers at Cal Poly and are in force today in their everyday life.... Two Valedictorians and one Salutatorian! You can't do that at a Unified School District! Peter P
