Each OpenSciEd unit undergoes an 18-month development process that includes external reviews, a robust field test, and revision. OpenSciEd will be releases units at the end of this process and after they are evaluated by NextGen Science’s EQuIP Peer Review Panel and receive a quality rating. Released OpenSciEd units can be found on the Access the Materials page and the reviews for all of our units are available on NextGen Science’s page.
