TESC - Letter of appeal for acceptance for applicant under 21

[Paul]

At what point is the letter of appeal to TESC introduced for an applicant under 21? As we understand it, we submit the on-line application & pay the $75.00 application fee. However, since the applicant is under 21 a letter of appeal is needed. Where does it fit in with the application process? The 60 credit hours for the Associate Degree in General Business have been completed so we would like to apply, have the CLEPS ect sent to TESC, receive the evaluation & apply for graduation for the Associates as a step towards the BS. Just not sure where the letter of appeal should be in the application process.
Thanks for your help!
