How to hire a Co-op student Contact the Co-op Department for student availability and program information. Provide a job description and salary for the position you want filled. AAPS will post the description for students or select students that perfectly match your requirements. Students will apply with a résumé and covering letter, which will be forwarded to the employer. Employers will select students they want to interview and contact the AAPS to make interview arrangements. Interviews can be conducted on campus, at the employer's business or by telephone. Employers make a coop placement offer to the successful student and inform AAPS.
