Frequently Asked Questions

How long is the Dental Hygiene program, and can you take it part-time?

It is a full-time program; five semesters in length.

If I am a foreign-trained dentist, do I have to take all of the courses in the program?

Any applicant who applies to the program and has not taken the prerequisite science courses within five years of application to the program must retake these courses. Due to U.S. accrediting guidelines from the American Dental Association Commission on Dental Accreditation, no dental coursework can be transferred to the Dental Hygiene program.

Can I complete the science prerequisite courses after the application deadline?

No, all prerequisite science courses must be completed by the deadline date of each year.

Will I be accepted into the program if I do not have a cumulative 3.0 GPA out of a 4.0 GPA in the prerequisite science courses?

No, the minimum cumulative 3.0 GPA is a requirement of the program.

Do I have to complete all of the general education courses prior to application to the program?

No, but we strongly advise applicants take as many or all of the general education requirements due to the rigorous schedule of the program. English 1101 is a prerequisite course; however, it is not calculated into the 3.0 cumulative science GPA.

If I am a certified dental assistant or a dental assistant who is certified in coronal polishing, sealants and application of topical fluorides, will I be exempt from specific courses?

No, students accepted into the program are not exempt from any courses within the Dental Hygiene program.

Do I have to have dental office experience to apply to the program?

No, applicants are not required to have dental experience. However, we strongly recommend shadowing in a dental office.

Is it possible to maintain a full-time job as a student in the COD Dental Hygiene program?

Due to the intensity of the program, it is recommended that students work a maximum of 10 to 14 hours per week.

If I have attended an Advising Session, do I have to attend another one?

You have to attend an Advising Session within the year you are applying to the program. You need to attend an Advising Session prior to the deadline date in the year you are looking to apply. ie. if you are looking to apply for a February 1 deadline, you need to have attended a session from February 1 of the previous year to February 1 of the current application year.

How many times can I take the PSB-HOAE Aptitude Test for the Dental Hygiene program, and what score do I need?

All applicants MUST take the PSB-HOAE Aptitude Examination prior to application to the program. Applicants are only allowed to take the examination once per application year. If you score above 50 percent in all five categories of the test, you should not need to retake the test. PSB-HOAE testing must be completed within two years of applying to the program in order for it to be valid for application purposes.
