The International Association for K-12 Online Learning

This is a site with many resources for K-12 online teaching and learning. When you submit a course to the TxVSN for review, they will use the iNACOL standards to review and approve your course. It would be a good thing to become familar with these standards. They are in a PDF file so you may want to download them and print them off.
