A+ enrollment is voluntary. To participate, students must complete and return a signed A+ Agreement Form (under Documents) to the A+ Coordinator. At such time, the student will be confirmed as an active A+ student. Students may sign up for the A+ program at any time between grades 9-12. However, seniors must enroll prior to their final semester due to the need to complete the 50 hours of tutoring.

Students who transfer to Linn High School after their freshman year will be allowed to participate in Linn High School's A+ program as long as they have transferred from another A+ designated school (as one of the requirements is a student must have attended an A+ designated school for three consecutive years prior to graduation).

After enrolling, it is the student's responsibility to fulfill all of the requirements of the program to become eligible for the financial incentives of the A+ program after graduation.
