Go to "My Communities" and click on the light bulb icon on the header and choose a unit you are working on from your list.
Clicking on the card for any unit will take you directly into that unit’s editing mode. Just below the title is the Achievement Standards link. Click on "Edit/Add Standards" to get started.
This will take you to a new screen where each category for your standards will appear at the top. Choose any year level and category to begin adding standards to the unit. Once the listed standards appear, simply check on each one that you want to include. If you change your mind about one, just uncheck it.
When you're done, click the X in the top left-hand corner.
All the standards you have checked off will now appear in the Achievement Standards section of the unit.
To add new ones, or uncheck ones you chose previously, simply use the same procedure above.
