A senior admissions staff told me some insight which may be helpful:
OT programs are looking for students who have a strong academic foundation, experience/knowledge in or of the profession, proven leadership exp and students who will bring something unique to the table (diverse major, culture, skill, etc).
If you think about these areas, you can use them as checkpoints during proof reading:
1) WHY did YOU choose OT. The actual answer is irrelevant as everyone has different paths and stories
a) do you have a reason and have you explored the profession to know what you're getting yourself into
b) are you able to articulate that reason (verbal and written skills are needed on the job and in ability to do well in the classroom, may show attention to detail and effort, professionalism, etc.)
c) if either a or b are weak but other areas are strong, these weaknesses may be reviewed and reflected upon after your interview
I have heard the following from other practitioners
2) Why will you be a great clinician
> can you make the school look good and will you be a pleasure to work with
3) Why will you be a great student
Hope this helps!
