As of June 22, 2021, recreational fixed-wing, rotary-wing, and multi-rotor RC pilots are required to take the free online TRUST training and pass the knowledge test to be certified to fly RC aircraft recreationally.
TRUST stands for Recreational UAS Safety Test.
The training and test are easy and I did it on my smart phone in 15-min. I’m sure that I could have taken and passed the test without reading the training text, but I took the time to read through the text so I could tell my recreational flying buddies, who aren’t big fans of the FAA,etc, what it’s all about.
You have to read a few paragraphs then take and pass a short multiple choice quiz about what you read. There are 4 or 5 sections and quizzes. If you miss any questions, they review the material and ask the question you missed again (I didn’t miss any questions so I’m not entirely sure about how they handle missed questions).
I have some very elderly RC buddies who may worry about taking the test but I doubt that they will have any trouble with it. There is no age limit (minimum or otherwise) for taking the exam. I think if you can read and understand English, you can pass the test.

The 2nd link is to UAV Coach’s website. I highly recommend them since they are who I use for my CFR Part 107 commercial UAV training. They don’t try to sell you other services when using their online TRUST training. Most of the other providers I checked, including the AMA, seemed to have ulterior motives for offering the free training and test. The Pilot Institute TRUST website seems good too.
