My son has attended Delphi since he was 3.5 years old....he is now 12! I'm so grateful that we invested in his education with Delphi Academy. The curriculum is like no other children are all different and learn at a different pace and this school accommodates this..... it is not a one size fits all solution which is so refreshing. The class sizes are small which enables the teachers to have individual one-on-one time with your child, which is priceless. When your child teaches you how to do math, the "new way" it truly is enlightening! The other great and rare teaching that Delphi focus's on is the importance of taking responsibility, and being accountable for your actions. This is all intertwined in a action packed, fun curriculum. All in all, I'm confident that my son has received the best foundation that he will continue to use and remember for a lifetime.

Our daughter has attended Delphi since she was 2.9 years old. How surprised we were when she began her reading program that very first year of school! Their simple step-by-step approach helped our daughter gradually and continually increase her reading ability and she`s now six and reading better than many third graders. She has also learned how to write all of her letters in cursive, has started multiplication, learned how to play piano and is super physically fit. all products from her time at Delphi. And she loves school. Not all parents can say that.

Delphi Academy of Boston is dedicated to helping their students comprehend new topics, and to learn how to learn - a skill that's needed not only in school, but throughout one's life. It's been two decades since I've attended, and I still use elements of their approach when I need to learn new things.

Delphi Academy was a God sent for my son. He was a bright first grader at another private school, but was not being challenged to meet his full potential. Upon his arrival at Delphi he was immediately evaluated and was placed in one of the best reading programs. Over the years he excelled, and along with his peers at Delphi, his reading and math assessments placed him at least one grade level above his age group. My favorite part about the Delphi academic program is the fact that while it is full of intensity and rigor, it is also designed to ensure subject matter mastery before moving on to the next level or topic. Essentially, each child can have their own guided curriculum and set targets to achieve along the way. Especially in the areas of math and reading. Delphi was absolutely the best decision and best choice for my son who is now in last year at the school. In addition to the excellent academic foundations that we have gained at Delphi, the support system and close community is also the best, and we will always be like part of the family. I would tell anyone who is looking for a strong foundation and development for their children to offer them the Delphi Academy opportunity. You will have a happy child, confident, bright and lifetime independent learner who is very fit for any academic challenges.

I have two children enrolled in the school. Every day I thank my lucky stars for having this safe, caring and enriching environment for my children to learn in. Over the years my son has become a confident, independent learner who knows the value of being able to apply what he has learned. He loves math, science, reading, phys ed and art and that love was built at Delphi. My five year old daughter can read, write all of the letters of the alphabet, knows their sounds and is already developing logical reasoning skills. She comes home with new songs every week and does not want to leave at the end of the day. I highly recommend Delphi for any family looking for a school with small class sizes, as the children are able to receive the individualized attention they deserve. Delphi is a school that their children will love.

One of the best investments that you can make as a parent is investing in your kids education. I looked at different private schools in and around the Milton area but finally decided on Delphi. It was their curriculum that set them apart from the rest of the pack. I was very impressed with Delphi's approach to learning, and their focus on teaching kids at their own individual pace. They put a lot of emphasis on reading and writing. It was amazing to see my 3 year old reading and writing so quickly. They also focus on making sure the students understand the meaning of the words that they are reading. In addition to reading and writing, Delphi Academy has done a great job teaching my kids math. Delphi Academy has an amazing teaching process and the results have exceeded my expectations. They take time teaching kids based on their level. Delphi doesn't rush kids or teach to take a test, as is seen in public schools. At Delphi they know that each kid is different and special and they give students the confidence in themselves to get better every day. Also, they do NOT have a religious agenda. I am Catholic, and as a parent I prefer to teach my kids our religious values.

My son has attended Delphi Academy for 5 years now and has flourished in the Delphi environment. A practical curriculum allows children the opportunity to be directly invested in their learning and allows them to see immediate rewards for their hard work. The educators at Delphi know exactly what tools to use in order to keep the children engaged and encouraged - we love them all! The reading program is simply amazing - my son's vocabulary is larger than many adults I know and he is only 10. He has grown more inquisitive and intrigued with each lesson mastered. It has been wonderful watching him thrive both academically, socially and physically. Delphi was definitely the best choice for our son.

My 6 yo son has been attending the Milton campus of Delphi Academy since he was 2.9 yo. At the end of seven weeks in summer camp he had passed the beginning stsges of knowing how to read! The education the children receive is second to none!
