OpenEd recently released its Free Assessment tool. OpenEd's assessment tool not only provides the question types required by the Common Core curriculum, but it also has some unique capabilities as well, such as suggesting videos to students who miss specific questions. It also suggests questions to teachers to add to their Common Core assessments.
OpenEd offers educators the largest K-12 resource catalog online today. Here's a couple of interesting videos about their new online assessment tool. Check them out!
