US Immigration from Argentina

Hello,

Hoping any Colorado folks who have gone through the driver's license process can help us out as I'm finding it very difficult to find accurate information online. My husband just received his EAD card and we'd like to get him a Colorado driver's license. We went through the application process online and got the print out for him to bring to the office. However, I'm also seeing some places online that says he'll need to take the written and driving tests. Do those need to completed before the appointment where he brings in his paperwork? He has a license from Argentina.

The first available appointments aren't until November so I definitely want to make sure we have everything we need for that appointment... I tried calling the phone line but they were not very helpful and I'm feeling more confused than ever. Thank you for your help!
