Keystone Credit Recovery offers students two ways to complete credit recovery units: online or through correspondence. Students enrolling in online courses receive an email with instructions on how to access their courses.
Keystone offers a year-round summer school alternative. Over 40 courses are available to students in grades 6 through 12, so students can master English, math, social studies, science, and Spanish, earn passing grades, and graduate on time with their classmates. Credit recovery course materials are available in online and correspondence formats.
