I can't find your request to read the other posts.
First off, there is no requirement for reading speed under NCLB. All of the NCLB stuff is based on the test scores.
I was going to say that the words per minute is just a benchmark....but that may not be true in your school district. (I am in SMSD and since they don't do honor roll in the 2nd grade I am guessing you aren't)
I know that the schools for some reason do put a lot of emphasis on reading speed...At our school that is ORAL reading. I don't know what evidence they have that this is critical---and since your son is on honor roll and has good comprehension I don't get what the big deal is. (I had a similar problem with my dd in second grade---she was actually reading 1.5 years ABOVE grade level and they said she needed to work with the reading specialist.)
Honestly, if I would recommend just having him read to you a lot this summer. Let him pick the books. Maybe he can read while you prepare dinner or right before bed. I don't think any reading tutor would be doing much more havin him read...From everything I have been told, the only way to increase the speed is more time spent reading....
I will also add that my dd was recommended for summer school every year until this year. (She is going into 5th grade)What is different this year? WEll the only difference I see is that her school is not the host site for summer school.
If you want to get him extra help, I would start with having his current skill level assessed. I think some schools are very 'competitive' and that may or may not be something you want to encourage in your child.
