Meaningless awards and affiliations
The badges you earned while you were a Boy Scout meant a great deal at the time. But they are not relevant in an employment application. On the other hand if you were a National Merit Scholar, that deserves a line. Put that right before the entry about your Fulbright Scholarship or Rhodes Scholarship. Ok, you get the point. Anything to do with academic achievement is something to be proud of. On a private school employment application academic achievement trumps just about everything else. At a minimum it should get you an interview. Remember: you will be teaching young people who want to learn. Your strong academic performance can and will inspire your students.
Everything in your job application should support the impression which you are trying to create in the reader's mind. "This is somebody we need to interview." You will be teaching young people. They will have enough off the wall influences of their own. The school would rather hire adults who can be exemplars and role models of steadiness and resolve. Their clientele, i.e., parents, expect that and much more. Mainstream hobbies and interests will not raise red flags. Include one or two on your application. Since you are being interviewed for a teaching position, it might be a thought to have a few titles of books you have read recently on the tip of your tongue.
Unless you are applying to be the fencing coach or some other athletic position, physical characteristics have no place in an employment application. The fact that you are 4'10" or are bald is irrelevant. What you can do for the school as a teacher is relevant. It is illegal to make "employment decisions based on stereotypes or assumptions about the abilities, traits, or performance of individuals of a certain sex, race, age, religion, or ethnic group, or individuals with disabilities, or based on myths or assumptions about an individual's genetic information."
In a private school job application your religious views may indeed be relevant. If the school requires a statement of faith and you are comfortable embracing its tenets , then by all means refer to your religious views as something which are relevant. However, if you are applying to a non-sectarian school, keep your religious views to yourself. Strictly speaking, religion is not something employers can ask about any way. It is illegal so to do. According to "Title VII of the Civil Rights Act of 1964 (Title VII), which prohibits employment discrimination based on race, color, religion, sex, or national origin" in hiring and recruiting, to name just 2 aspects of the employment process in which discrimination is illegal.
Nothing will get you in more trouble than listing credentials you haven't earned. Every credential you list will be verified. So if you state that you graduated from Princeton but actually only attended a seminar there, that will catch up with you sooner or later. Listing credentials which you don't actually have could be a career limiting event as well. Academic honesty is paramount in any private school.You will find that academic honesty is enshrined in the school's code of conduct and policies.
