Can I make it to the class? This is a pretty major question. If you can't make it because it's too far away, or the day/time isn't right, then you shouldn't switch to that one. Luckily the "too far away" one won't be an issue since Sensei Pytel and I will be staying in the area for the foreseeable future.
Who is the instructor? While there have always been great benefits to working with different instructors, if you have a connection with a certain Sensei, or enjoy their teaching style you may want to switch to a class that they run. At the same time, don't be reluctant or intimidated to work with another Sensei in our dojo. They each have different strengths to pass on to you.
What do I need from a class? Some classes are designed to fit the needs of beginners or people just trying out karate classes (I.E. once a week afterschool programs, the intro classes, etc.). Some are for students who have been introduced to Shobayashi-Ryu and want to devote themselves to more serious training (I.E. The teen adult classes). Seriousness, skill, and maturity have a lot more to do with your readiness to join the teen adult class than your actual age. See my previous post on this subject.
Luckily, one aspect that students of our dojo don't have to worry about is what will be taught in the classes. In our dojo we teach all aspects of Shobayashi-Ryu to students. In many other dojos there is a specific night for kata, a specific night for sparring, etc. This is sometimes a problem because imagine you go to karate twice per week. Monday and Wednesday. Monday is kata night, and Wednesday is sparring night. Now let's say you have to miss Wednesday nights for three months because of football or another sport. This means you haven't gotten in the ring for three months!
I look forward to seeing each student in each of the classes!
