Interviewing for job positions is incredibly competitive, so interviewees want to market themselves the best they can. I would not go into an interview unwilling to do some sort of extra curricular activity, for it comes with the territory of taking on a new job. However, that does not mean you have to agree to everything. You should go in knowing what you are willing to do, so if the principal asks, "Would you be willing to be an assistant basketball coach?" you can say, "I do not know that I would make an impact as a coach, but I would enjoy working with students outside of class. Perhaps I could be a class adviser."

I do not think you should agree to something that you are not interested in doing. I made this mistake when I was hired for my first teaching job. I agreed to a cheer coaching position and after two years of complaining and feeling exhausted all of the time, I finally stepped down and I have been happier than ever! With that being said, you do want to make yourself marketable and show the principal that you are a team player, so you could always say something like "For my first year I would like to focus on being the best teacher and supporter of students. I am 100% open to any responsibility that allows me to help students academically if that is available." It is also best to have such a strong resume and interview, that they will want you - coaching job or no coaching job. :)

You're probably going to have to do something, so if you aren't interested in doing anything you may want to reconsider being a teacher. It, unfortunately, just kind of comes with the territory. I would mention thinks I want to do or would be good at doing. If you are going to have to do something, at least make it something you will half way enjoy and succeed in. This will let them know you are willing but also understand what your interests/talents are.

I think you should only agree to extra curricular activities that you feel ready to take on. If your principal asks if you are willing to sponsor clubs, let them know it will be depending on the subject and time involved. You do not want to agree to taking on extra curricular activities and then not be able to handle it once the time comes around.

Coaches need to have a certain amount of passion and drive, Being you do not want this responsibility do not feel pressured to except extra roles.

Maybe suggest you will give it a trial run or try it out

I would say something along the lines of "I'd love to help out, in time when I am comfortable in my position." This way you're not saying a complete no but you're leaving it open to interpretation and setting your boundaries.

Although it makes yourself highly marketable to agree to extra-curricular activities, if it doesn't suit your personality, I would not agree to it. I would however, make it known that you are willing to help outside of the classroom in an area that better suits you. (Offering tutoring, perhaps?)

I would be more than willing to dedicate some time to coach or sponsor a club. Though if I needed to say no, I would tell them that I do not have an adequate amount of time to dedicate to that.

I agree with the first solution. You want to be open and willing to do something, it'll make you more marketable during the interview. Think about what you'd be willing to do and what you think would make an impact and when asked about it in an interview that's what you tell them.

I would be honest with how I feel. Whether if it is a lack of interest in the sport/club or a lack of time, honesty is the best policy. You do not want to wear yourself too thin with too many activities or responsbilities and you do not want to invest yourself into something you are not interested in. Whatever you do, do it with a passionite heart.

Teaching jobs are hard to come by! You want to make yourself marketable and willing to cooperate. If it is a job you want, then I wouldn't think that helping coach would stop you from accepting the job.
