We are aware of and investigating an issue where districts/school who are licensed for mCLASS Lectura only are seeing disruption to the online management of student assessments. Teacher-led assessments remain unaffected, but students may see that assessments are not assigned. Our Product team is working diligently to resolve this issue and we will provide updates to our progress here. We appreciate your patience!
