OpenEd is an online catalog of educational assessments, homework assignments, videos, games and lesson plans aligned to every Common Core standard and several other standards, and includes the only open source formative item bank. The site offers the ability for teachers to assign resources to their students online, letting students take assessments, do homework etc. on their own computers or tablets. Assignments done online are graded automatically and presented to the teacher in a mastery chart. OpenEd's slogan mentions "assessment to instruction" meaning, formative assessments given on OpenEd can access OpenEd's large catalog on a per student basis to recommend the right resource to each student individually. The company has stated that functionality of searching the site and most of its resources are free and will continue to be free going forward. However, the company is also distributing premium content from publishers such as Pearson and Houghton Mifflin Harcourt to teachers for $9.95 per month.
