Momma Bear, thank you very much. This is the school's accreditation statement:

Accreditation:
We are accredited by The American Montessori Society (AMS), the Southern Association of Colleges and Schools (SACS) and The Commission on International and Trans-Regional Accreditation (CITA). We are affiliated with the International Montessori Council. Under the guidance of Montessori teachers the children progress with excitement and confidence.

It really seems perfect for him. I just wish it wasn't so darn expensive! It's worth it for him though.

I believe that my daughter (mostly) and son each have difficulty with auditory discrimination and processing and probable attention difficulties. In fact, when my daughter was around seven, two different educational psychologists deemed that she was 2E and I was warned that her compensation abilities would fail eventually by late elementary or middle school. (So we skipped her up a grade into a more advanced per grade school)

This 2E conclusion was reinforced by a developmental pediatrician and by a university educational testing department when she was in 5th grade. (So we looked for the most ambitious high school program that we could afford within driving distance)

Not to jinx the situation, but dd15 is doing extremely well at a challenging school where she takes eight classes plus an additional computer programming class through Gifted Learning Links. She leaves at 5:15am in the morning for swim practice and arrives home around 6:00pm on average after her extracurriculars ,including a club that she founded and leads, then does homework until bedtime. She is kind of a grind on weekdays, but has plenty of social invitations every weekend and maintains relationships by multi-tasking communication with friends while she studies and completes her schoolwork.

This sounds like a brag, and I am terribly impressed by her (and her friends), but my point is that I don’t think she could have achieved this well had we left her in the original, under- challenging environment. I had always said that I would not be opposed to seeking medication for either kid, but I intended to try a different approach first.
I hope our BTDT experience helps.

You are very welcome

Hi there JenSMP,
You are really committted to getting what is right for your child and I honor your dedication to your family! I love the Montessori education model, best wishes with that. I am not a medical professional and won't comment on meds. One thing that we have found tremendous success with is the Nurtured Heart Approach to engaging with our child. This after nothing else was helping; NHA changes everything. You can get more info. at www.difficultchild.com or www.nurturinggreatness.net.
I posted about it before in a different forum too.
Best.

Thank you NHAYEAH. I appreciate the recommendation. I've heard the term, but I don't know what the Nurtured Heart Approach is all about. I'll check it out this weekend and see what I can find. Is there a book? I need another one of those, let me tell ya! No, seriously, if it will help, we're all for it. We just want a happy boy!

Just found the other info in a different thread. I'll definitely get the book. Thanks again everyone for your help. I'm back to thinking maybe it's not ADHD. Though, I've been here before. Ask me what I think tomorrow! He is very intense and difficult, regardless, so it sounds like the book is a good place to start.
