There is no minimum age for small game in CO.
Big-game is 12.
I'm a HE Intern in Grand Junction. Anything below 10 yoa we worry about and 8 is right on the edge and 7 or under is really asking for to much.
Last week we had 3 failures....(2) 8 yoa kids and a 13 yoa kid.
The failures were a boy and a girl. If you can't pass our coarse, then you can't pass it. Every Q on the test has been stressed 2-3 times and on the review, the main instructor gives them about 30, out of 50, answers for the test.
Also, at the start of each day, the main instructor does a review of everything we taught the day before that is on the test.
The boy that failed, was in the class by himself, and the girl was sitting next to her aunt (her mother and brother were in the row behind them).
I think that the kids didn't take notes, or make a star in their book, next to something, when we say, for the 3rd time, for example, that the expanding gas pushes the bullet out the bbl. They count on remembering it, but don't.
The best courses, for learning, are the week long week-night courses. They are also the hardest to work into a person's schedule.
The easiest course for you to take/schedule are the 1 day computer/internet courses. I don't have any experience teaching them, but they are 1 day long and I don't think that there is a test. It is a home-based. They work through a course, on their own, at home. But, there is a test on the computer, that they must take, and pass, and they print out a certificate when they take the test and then bring it in. They may or may not have another test in the classroom.

They all cost $7-10 and some of the Internet courses charge for the internet part (which is additional).
The shooting...how much time do you think that I have to actually look at them when I have 10 people shooting and 2 of the guns won't extract (Winchester ammo and before that it was Remington, and 2 classes ago I ran a snake through all of the guns before we shot and/or ran a rod through all of the guns (same failure rate), oh yeah, we had a Sportsman's Warehouse guy give us some CCI...it worked perfectly). So, my point, if she can load a single shot .22, by herself, shoot it, and keep the dern thing pointed at the metal trap, she'll pass. The biggest thing is, finger off the trigger until you are ready to shoot. We don't care if they hit the paper, or not. But, if that gun comes out of the stall, or gets pointed at anywhere but the trap, then they are gone.
So, to answer your question...if you sit next to her, and keep notes for her, and make a star in her book, next to the gray rectangle, on page 329, that is going to be on the test (you'll know because we go over it 3x), then review those things w/her, then she'll get a 90+ on the test.
