All phone calls are handled by our Customer Service Department. The first available representative will answer your call in the order it was received. 

Unless you are calling with general questions about our program, make sure you have your Family ID or Student ID handy; our representatives will not be able to help you if you cannot provide this information. If your call requires a response from another department, that department will be notified. If the representative is unable to answer your question, he will take your name and phone number and call you back.

You may use our Customer Service Call Log to record all relevant details of your call.

Faxed correspondence should be submitted with the same information as mailed letters—include your name, Family and Student IDs, and the department to which you want the fax directed (see above).

Remember that a fax, by definition, is a photocopy. Faxes are not originals. Do not fax a document (e.g., CAT answer sheet or Westpoint application form) that must treated as an original; mail it instead. Similarly, if you want us to fax a document (e.g., a transcript) to you or another school, make sure a photocopy will be accepted prior to making your request.

Do not fax coursework or tests to CLASS. Course materials must be received in their original form. Tests and R&I sheets will not be accepted by fax unless prior approval has been granted.

To contact CLASS by fax, use the following number.


 (847) 259–2443

Enrollment Applications and Bills

Faxed enrollments must be paid by charge card (VISA, MasterCard, or Discover card). Payments for other services may also be made at this number, provided the payment is made with an acceptable charge card.

You may fax your enrollment applications and payments to the following number.

All written correspondence should be sent to the address listed below. Remember to include your name, Family ID, and Student ID, as well as the appropriate department to which you want the letter directed, as shown above. If you are not sure which department should receive your correspondence, send it to Customer Service.

Do not send any coursework with your correspondence; mail it in a separate envelope. Responses to letters submitted with coursework may be significantly delayed.
