What Our Clients Say

“One of the most consistent feedback comments that I received in my end of the year course eval was some variation of ” thank goodness we have the lab! We were so prepared for the speaking part of the exam!” I am convinced that Our SANS lab is the key to my students’ success.”

Ms. Berg

“We had a GREAT year.  No problems at all.  Everything was recorded and submitted to AP immediately via their new upload system.  Scott, Lynne and I were all really happy this year!  Soloist really did work perfectly.”  

Mr. Wildman

I highly recommend CTS (Chester Technical Services, Inc) for their excellent guidance and support.

Whether we are testing 3 students or 130 students per exam, the level of service provided is excellent. With a member of CTS joining us on exam days, we are secure in knowing that the administration of our testing goes smoothly.
