I went to my board in the Brazilian first league as GRE and requested that a coaching course be compensated. They initially rejected it but I countered and said "If I can keep this promise can I get a coaching course funded?". The board went on to say if I could ensure that training was properly staffed for a full month they would fund a coaching course for me upon promise completion.
I completed the promise and it shows completed in my "Promises" tab but the coaching course has not been granted as of yet. I have simmed 7 days after the promise completion.
