Enroll in the school's high school diploma program. Find a community or technical college that offers a high school degree completion program. Contact the admissions office for help to enroll in the program. Be prepared to pay any associated application fees, as well as provide any school records you have.
Apply for financial aid. Talk to the school's financial aid office if you need help paying for school. Tuition and books alone can be very expensive and you may need the extra financial help to pay for room and board. Be sure to tell the financial aid counselor that you are planning to stay on campus; this can open you up for additional financial aid to help you cover the additional cost.
Contact the housing office. Contact or visit the schools housing office and ask to speak to a housing officer. Ask the housing officer if being enrolled in the high school diploma program excludes you from being eligible for on-campus housing. If your school also houses a charter high school, be sure to make it clear to the housing officer that you are not enrolled in the charter school (for teens) but the high school diploma completion program (for adults). Many schools don't restrict housing eligibility by program enrollment but by age and enrollment hours, such as being a full-time student vs. a part-time student.
Apply for housing. Request or pick up a housing application package from the housing office. Complete the forms in the package and submit the completed package back to the housing office before the deadline and with the application fee. Be aware that this application fee is often nonrefundable and does not guarantee that you will receive housing.
Sign the contracts. If you are approved to live on campus you will be required to sign a housing contract and a payment agreement. If you under the age of 17 you will need an adult to sign these along with you. The payment agreement varies, depending on your school's housing policy. Some community colleges assign housing like tradition universities--a flat-rate that must be paid at the beginning of each semester. While other community colleges have opted for an apartment leasing format, where the student signs a lease for a contracted period of time, such as 12 months to 48 months, and rent is collected from the student each month.
