My DS13 has been in AVID since 6th grade (he's in 8th grade now). If we had it to do over, he would not have taken it. It may be different at other schools, but it has not been very good at his middle school.
I had never heard of it before going to the upcoming 6th graders orientation. It seemed like something that my DH & I thought DS could benefit from. We were told that he couldn't just sign up for it, that he had to be invited and then had to pass an interviewing process to be accepted. You can imagine our surprise and happiness when he was invited and made it thru the interview.
In the almost 3 years that he has taken it, I don't think he has learned anymore about being college ready than any other student not in AVID. They have changed teachers every year (he's on teacher #3). They rarely have guest speakers as promised. They are graded on how organized their binder is, speaker notes and tutorials.
The tutorials are ridiculous. In 6th grade, the tutorials were based on problems that a student might not completely understand
for an upcoming assignment, test and/or quiz. They would discuss the problem as a group to try to figure it out prior to having to do it. Starting in 7th grade, with a different teacher, this processed was changed. Now, they discuss problems
that were missed on an assignment, test and/or quiz. To these students, this process kinda defeats the purpose. It's not as important to them after they've already been graded on it.
We've also struggled with the organizational part of AVID. Everything has to be kept in the same binder. When individual teachers request a folder for their class, it doesn't apply to AVID students. They just have to dedicate a section in their binder to that class. It sounds like a great idea, however, it makes the binder HUGE and it's difficult to find a backpack that you can get the binder down into easily. Also, because the binder usually "just fits" into the backpack, the binder gets worn out faster from trying to put it in and take it out of the backpack. We've gone thru more 4" binders and backpacks.
High school AVID may be totally different. Even middle school AVID may be different in your area. I just know, that for us, the experience hasn't been anything like we were expecting.
The high school that DS is zoned for doesn't have AVID, however, he wouldn't take it if they did. We have already been told the core classes that he's been assigned to for high school and I'm happy to be able to say that he'll be taking Honors English, Honors Algebra I, Honors World Hisory and Honors Intro to Physics. I don't feel like AVID contributed in any way to him doing well enough to be put into these classes.
Good luck to your DD in whatever she decides to do. Again, my opinions are only based on our experience with our AVID program.
