A personal statement is a professional short story about you paired with a résumé, explaining why you want to work somewhere and how they would benefit from your skills. It is your chance to expand on your résumé to give more depth to your qualifications.
Prepare to tailor every single statement specifically to the place you are applying. While you may be able to create a rough template, one generalized personal statement will not be strong enough for any institution.
First, review the institution's requirements for the personal statement.
Second, research the institution's mission statement, values, and staff.
Third, brainstorm unique/unusual and motivated stories that are related to you.
