Dental Assistant School Policies

Class Hours

Assisting classes run for twelve weeks. Sessions are available on Saturdays 8AM to 5PM with an hour for lunch. Certificate classes are usually held on Fridays and Saturdays. The school observes and will be closed for all legal holidays. Classes which fall on such a day will be rescheduled for the following week.

Conduct & Dress

Students are expected to act in a professional manner at all times both in class and during observation or externship. Upon admission, students must sign an honor code of conduct which outlines the standards of behavior that are expected. Proper attire must be worn in treatment rooms and during clinical exercises. Professional appearance and attire will be discussed in detail during your orientation.


A low student to instructor ratio is maintained by keeping class sizes small. There are no more than 10 students per instructor and most clinical units will have additional teaching assistants for a personalized learning experience.


DA1 Classes at DSI are designed to follow an accelerated curriculum. Because of this, it is very important that you commit your class time on your schedule and not miss any modules. Modules may only be missed in the case of an absolute emergency. Should it be necessary to miss a module, please give as much advance notice as possible. Students may miss only one module for a documented emergency. You may study the material at home and still take the module exam the following week to keep up with your classmates, however, in order to receive your certification, you must audit the missed module during the next available session. If you did not pass the examination for that module, you may retake it only after you have audited it. OSHA, CPR and Radiography modules may not be made up. Should you fail to attend these modules, you will need to take them at additional cost with us or provide proof that you have obtained those certifications elsewhere in order to receive your DA1 certificate.

You are expected to be ready to start on time. Tardiness affects not only you. The disruption affects your classmates as well. A consistent pattern of tardiness will not be tolerated and you may be asked to withdraw from the course without a tuition refund.
