Candidates may have been provided a Voucher Code from their University. A Voucher Code is not the same thing as an Authorization Key.
A Voucher Code is the code candidates can use to obtain their Authorization Key from edTPA.com.
Once candidates have obtained their Authorization Key from edTPA.com, they can use the Authorization Key to transfer their portfolio to Pearson inside Edthena.
An Authorization Key is formatted like this - "A12B-C34D-GHIJ-F567". 16 characters, with every 4th character separated by a dash.
