My oldest boy went to MBMA through 1st grade, the 2nd one went there through Kindergarten. My youngest is at MBMA now in the K-side. My oldest is now in 4th grade at Jonas Salk Elementary now. He always tested several grade above while at MBMA, but when he went to public, he’s essentially grade level, at least that was what his grades came out to be. For his 3rd grade State standardized test, he got 100% on both Math and English. So, I felt like both of my boys are exceling just fine at public school compare to MBMA. I do love how MBMA set a pretty strong fundamental for them and got them to love learning. So, I have no problem w/ MBMA, which is while my daughter is going there now. But, I’m also happy with their public school as well. So my daughter will be going to public school for 1st grade as well.
I do love the ability to walk them to school and save thousands of $ every year, which pays for their many extra curricular activities. The lack of commute also allow them to do more activities as well. Just something you might want to consider.
