There can also be issues with the slide rule moving from year to year. It's not always that if you meet X criteria you're in the program. Depending on the district and school, they may only allow Y number of students in a program, so meeting X criteria this year doesn't necessarily mean next year the criteria won't be X+10. So they may tell you what the assessments used are, just not what the cut-off point is as it may vary from class to class, year to year.
