Refund Policy

Note: This provider has a temporary cancellation policy for COVID-19 related cancellations which is as follows: 

All of our classes are offered live online and any student with a computer and an internet connection can take class from their home or anywhere else they feel comfortable. For customers who are concerned about COVID-19 with regard to attending classes from one of our computer labs, please know that you can switch to attend from home up to the day before class. We just ask that you notify us so we can send them class connection information and inform the center staff that they won’t be coming in for class. 

With regard to our computer labs, each one holds a maximum of only two students per room so no student will need to be in close proximity to any large group of people. We’ve also asked the centers that host our computer labs to disinfect all keyboards/mice/surfaces, etc. after each use and requested that they provide hand sanitizer to our students. That being said, we definitely understand if a student would feel more comfortable taking class from their home.  

We purchase and ship books to students two weeks before their class date and we are charged for any computer lab booking if not cancelled within a week of the booking date, so we would not be able to fully refund a student who wants to cancel less than two weeks before class without incurring a financial loss to us that we would not be able to recover. With the attend from home option, students do hava a choice to stay home and still get their training. Students can also choose to postpone their training to a later date if they wish. 

---- 

Original cancellation policy (non-COVID-19):

You can cancel or reschedule your registration without penalty or charge provided you give notice of 10 business days (M-F) or more days before the start of my class.

If you request to cancel or reschedule your registration 10 Business Days (M-F) or less days before the class start you will be charged 100% the course fee and will not be entitled to a refund. You have one (1) opportunity to use our Make-Up policy to have those funds applied to a later class date.

You cannot change your class location ten (10) Business days (M-F) or less before the class start because Certified Staffing Solutions has shipped training materials and provisioned resources. Location changes requested prior to that timeframe are subject to availability and may incur an additional charge.

Should Certified Staffing Solutions need to cancel your class due to insufficient enrollment, or postpone it due to events beyond their control, Certified Staffing Solutions will notify you as soon as possible. In such cases, you may reschedule to a future class date at no additional charge or receive a refund for any money on account relating to that registration.

Travel arrangements and costs are the sole responsibility of the student. Certified Staffing Solutions suggests obtaining refundable reservations. Certified Staffing Solutions classes are confirmed approximately 14 days before the start of the class. We cannot guarantee class commitments before that window of time. Certified Staffing Solutions will not be responsible for any cancellation costs incurred, including but not limited to, airline/mass transit tickets, hotel reservations and so on.
