About Laurie

Laurie Semple is the Program Coordinator for the Registered Dental Assistant (RDA) Program in the Health Sciences Department at Tarrant County College Northeast Campus. She oversees a selective full-time certificate program accepting up to 16 students per cohort, spanning two semesters for a total of 25 credit hours. The fall semester includes 13 credit hours of didactic classes over 16 weeks, while the spring semester covers 12 credit hours: the first 8 weeks for labs and classes, followed by 8 weeks of clinical externships totaling 224 hours arranged by the program coordinator. Classes and labs run weekdays from 8 a.m. to 6 p.m., with a minimum passing grade of 75%. The approximate cost is $2,824, including books and uniforms. Graduates receive the RDA Certificate along with Texas State Board of Dental Examiners Registration and Nitrous Oxide Monitoring certificates before beginning externships, preparing them to work under dentists and with hygienists.
