One of the great things about Starfleet's "Architecture" profession is the rigour which is applied in the process of advancing through the various grades. This is further enhanced by the requirement to re-certify every three years - and this means showing that you have attended relevant education, showing that you are using and extending yours skills, and showing that you are giving something back to the profession.
The Gorse Fox is at the highest level of certification, and this morning has received an email reminding him that he needs to re-certify before November to retain his qualification. (Yes, you can drop back down through the ranks as well).
He chuckles to himself as he deletes the email. Another hoop through which he no longer has to jump!
