No, if I was in this position I would wait until I had another teaching position already in line. Therefore, when I tell my current school I am leaving they too can start interviewing other applicants and start to fill in my position. You never want to leave still jobless just in case it takes you another year longer to find a job your not kicked out of your position before times up.

I say no, its just like any other job, after you have been given the other job. You don't want to suffer the indifferent responses you will receive at the current school if you don't get the job.

Until the reality of the new job comes (being offered) I don't think it's necessary to let them know. If you are close with your administration and feel they will be receptive, I don't see any problem with it. But if you feel they will be ugly about it, definitely don't. Usually there is the question "May we contact your current employer? If so/not, when?" on the application. I think that the interviewer understands that if you mark "no" that there should be no contact until you give the go ahead. You never want to leave a job with any reason other than giving people good things to say about your performance.

Absolutely not! :) I am currently in the same boat. I am applying for a new teaching position and I have even interviewed. I do not plan to notify my school school/district until I have confirmed my new position. I say this because I do not want any unwanted tension during the current school year. Also consider whether or not the new position is in the same district (transfer).

As an employee, you should work to develop a strong, positive, working relationship with school administration. Most schools will contact at least one of the references listed on your resume. Before applying, be open/honest with your administration and inform them that a new position has been posted and you are interested in applying. Ask if they would be willing to allow you to use them as a reference. It is critical that you be thankful and appreciative of the opportunity to work for them and be willing to provide just cause for your desire to switch schools/positions. To provide you with a few examples, I began my career as a sixth grade special education teacher. My intent upon graduation was to teach high school U.S. history. Additionally, I was teaching at a school 45 minutes from my home. My goal was to transition into a general education setting and move closer to home. The administrative staff were always supportive and willing to serve as a reference. In my sixth year as a teacher, I am still at the same school, but have been moved into a general education class and teaching eighth grade Georgia history. We have changed principles once in that time and I still have a great working relationship with each administrator that would support my decision to pursue a high school job, if one became available.

You are not inclined to expose this information.

Yes, you want your current school to prepare and start looking for teachers who can fill in after you leave.
