Online Proctoring
The four-hour CLS examination is offered to US and Canadian residents via Online Proctoring through our testing vendor Webassessor. Applicants will be required to use either an internal or external web camera to complete their exam. The ACCL allows use of both camera types.
When registering for an exam there are a few steps applicants must complete:
- Download Sentinel Secure™ on the computer you plan to use for the examination.
- Create your biometric profile. This helps us confirm your identity.
- Launch and complete your exam.
