Content Update: Summer 2022 updates to 3rd, 4th and 6th grade math courses!
We’re excited to share that enhancements to several of our math courses were released in summer 2022. Edits were made to this content so it better aligns with grade standards, and to make sure students receive the right amount of challenge for their grade level. One consequence of these content updates is that it may impact some of your students’ Mastery percentages.
When we add new or remove old content, student Mastery percentages might change because the overall number of skills available in a course changes.
 For example, instead of mastering 90 out of 100 skills, after an update a student might have now mastered 90 out of 110, reducing their Mastery percentage from 90% to 82%.
 With these specific course updates, we expect that student Mastery percentages will change very slightly.
 The maximum changes are listed below for each course, with the highest possible change in one single course being a 7.8% decrease.
The details about the specific changes to these courses are listed below:
