The R.E.A.D. registration is a per-pet addition to your existing NCTD certification - as long as you remain an active NCTD volunteer your R.E.A.D. registration is maintained. To obtain your R.E.A.D. certification you purchase the training materials from ITA. Complete the at-home training, fill out their registration packet, and mail it in with a copy of your NCTD registration and fee. Then just sit back and wait patiently with your dog next to the mailbox for your R.E.A.D. registration card to arrive!
You can find further information and registration instructions available at the Intermountain Therapy Animals website.
Note that since NCTD is a R.E.A.D. affiliate the registration fee is reduced somewhat. Don't forget to mention that you are affiliated with NCTD when you fill out your application.
R.E.A.D registration is good for the life of your pet - as long as he/she is an active therapy dog as well. The only thing you have to do to keep your R.E.A.D. registration current is to mail ITA a copy of your NCTD renewal every three years. If you have additional NCTD-registered pets that you want to register for R.E.A.D. there is a members-only form on the ITA web site that you fill out and send in along the a copy of that NCTD registration. There is a nominal fee for this but you don't need to purchase any additional ITA training manuals.
