How to use Modernstates voucher

[homeschoolmom1]

This may be a stupid question, but how do you use the Modernstates Voucher code? This is for our son who is under 13 years old. Isn't there  a way to call CLEP or something to register him? Thanks.

My understanding from reading the website is that you have to call to have a CLEP account set up for him, and then you should be able to register him online. Here is the phone number: 866-630-9305
