What is a good pass rate for students?

Imagine Math is designed to help students build proficiency and fill in learning gaps in math concepts.  Each student will have a unique experience within Imagine Math as far as remediation and reaching goals.  Overall, a student should strive to pass 30 lessons throughout the course of the year while progressing toward a 70% pass rate on their grade level lessons.  The grade level lessons will pertain to those on their assigned pathway.  

For example, a fourth grader who is working on a 6th grade pathway, will be striving to maintain a 70% pass rate for the 6th grade pathway (in which they are working).
