The 6-foot-5 quarterback from Tom Clark High School in San Antonio pulled the trigger after getting to experience UA during a visit to the team's spring game.
"I went and visited for the spring game and it was fun and everything," Kern said. "I have a great connection with Coach (Frank) Scelfo and I just had a good feeling for everything.
"I loved it, I really did. I wanted to commit while I was up there, but I promised myself I wouldn't commit until after spring ball. I ended up breaking that because I committed when I came back.
"I'm really happy, it just felt right, so I decided to do it."
His relationship with quarterbacks coach Frank Scelfo was one of the key factors in the soon-to-be senior's decision to commit.
"I have a really good relationship with Coach Scelfo," Kern said. "I call him a few times a week and we talk. I've read all of the stuff he's done and all of the places he's been and all of the quarterbacks he's put in the NFL, and I'm excited."
In fact, his most memorable moment during his visit to Tucson came from spending the afternoon with Scelfo and the rest of the quarterbacks prior to the spring game.
"My favorite part of my visit was going to the quarterback's meeting with the four quarterbacks and then walking out to the spring game together," Kern said. "I was having people running up to me and asking me for autographs, it was fun."
With just over 10 months to go until Signing Day, Kern is happy to have given his commitment to the Wildcats and put an end to the recruiting process.
"Right now I have an offer from UTSA," Kern said. "I'm pretty solid to Arizona. I'm ready to focus on my high school team. I owe it to my teammates to focus on the season, so I'm happy about that."
With Kern, Arizona is getting a player that describes himself as a bit of a dual threat quarterback who takes pride in forging solid relationships with his fellow teammates.
"My strengths are that even though I'm so tall, I can run pretty well," Kern said. "I throw pretty well and I always have a good connection with my teammates. We always have a good time and I think that translates out to the field."
As far as what type of quarterback Arizona is getting, Greg Powers of Scout.com has had the opportunity to watch Kern and writes the following:
"Kern has a nice frame, no doubt about it. In the day and age of the spread quarterback he has a little bit of everything to work with. He has some ability to run when need be and he has the arm to work on the underneath game.
"He will need to work hard to keep developing arm strength. On his deep balls he tends to underthrow and I think much of that is because he does not yet have the pop to get that ball down the field on the more "violent" throws.
"I like the fact that he can go under center and looks good taking a drop, an art that is harder and harder to find as the days of that spread become more prevalent. I also like that even though he looks like he has a long release he seems to get rid of the ball quickly.
"As his arm grows stronger I think that you will see a quarterback who can do a little bit of it all, but at this time he is still very raw and his numbers on the field are not going to blow you out of the water. You want to see a QB in high school complete up over the 60% mark and Kern is just over the 50% clip and only has a +2 on the TD/INT ratio.
"I think he comes in gets a red-shirt year and grow in the program. I would compare him somewhat to Drew Allen who also came out of San Antonio and signed with Oklahoma a few years back. He was about 190 as a junior and 205 as a senior. After one year at OU he was up to 230. Allen had a little stronger arm and was a little less raw, but I see similarities between the two from a developmental standpoint.
"I think the Kern you could see 3 years from now would be different from the one you see right now.
"At this point in the game I feel like this is a solid pick up, because he is raw with upside and I think that Arizona will sign more than one QB in this class. Kern will not scare other top QBs away, but will compete with any of them on the roster once they get to school."
