I would recommend contacting the school and/or district for that answer.
Thank you for reaching out for assistance on the PowerSchool Community!
The school district requests PowerSchool for the attributes required on a form. So, as @DanM3 said, I'd recommend contacting the school regarding this and they will be able to assist you with selecting the right option and they would be able to request the necessary changes on the form if required.
Please do let us know if you have any further queries.
