Lori,
Sarika can probably confirm this, but if memory serves me well, the System Info would drop the last group of characters from the license key to prevent it from being easily copied. I believe this was true in all versions of the suite, not just education. If it was part of a large/district purchase, somebody there may be able to look it up on licensing.adobe.com (or Sarika may be able to help).
