I think safeties also need to be what options your child will be positive on attending. To me, each and every option needs to be something that your child will accept with enthusiasm. It doesn’t do any good to have a college that accepts 100% of applicants that your child will not go to or is not at least minimally positive about. Maybe it is better to say My plan is to attend school #1 if accepted. If not, then I will attend school #2, etc… It might get to a point that after school # 8 or #10 on the priority list, which might be considered a high match or one that has a 60% acceptance rate and your child is well above the 75%, but not a gimme 100% safety. After a certain desired school, the plan may be to take a gap year and work or volunteer and take a few college courses to enhance your resume. The important thing is to not just have a list of schools, but a priority plan.
