Are Basic Reading and Proficient Math only included in the more Deluxe Upgrade?

Here's how to think of it. CCSS measures were part of the Deluxe upgrade. Anything formerly known as CCSS has changed but not their account designation.

The measures formerly known as CCSS Reading have been re-named Basic Reading. Those formerly known as MCRC Reading have been re-named Proficient Reading.

The measures formerly known generically as “math” have been re-named Basic Math. Those formerly known as CCSS Math have been re-named Proficient Math.

So Basic Reading and Proficient Math are part of the Deluxe package.
