3.) Where do I take the exam?

Computerized Testing Information

The CLS exams are administered by computer through Webassessor Testing Centers. Exam candidates approved to take the exam are given a scheduling permit by way of an email which enables them to schedule their testing appointment with the date and time of their choice. Exam dates and times are dependent on each Webassessor Testing Center’s hours of operation. Once you have selected your testing center, the date and the time of the exam is dependent upon the availability of that specific location. You must schedule your exam 48 hours prior to taking the exam.

Unless special accommodations, requested under the Americans with Disabilities Act, have been arranged you will have an allotted time (4 hours for the CLS exam and 2 hours for the BCCL exam) to complete the exam.

4.) What if I must reschedule my exam date?

If you need to cancel or change your testing times you must notify us more than 72 hours before your actual exam time. If you cancel after the 72 hours regardless of reasoning, there is an additional $95.00 seating fee that will be charged back to you. No exceptions. Please take this into consideration when choosing your test date/time.

5.) How quickly will I receive results?

Generally we will have score reports to participants 6–8 weeks from the date of examination. Exam results are confidential and will only be released in writing to the registered examinee

6.) What if I fail?

The LCC exam may be taken up to 3 times upon filing a new application and paying the re-examination fee each time. If a candidate fails three examinations, eligibility is withheld for a period of two years. The LCC retake fee is $200. A retake must be taken within one year of failing the exam, or a new application and full fee must be submitted.

7.) Is there a deadline for completing the LCC Exam?

LCC Examinations must be completed within one year of application submission. For example, If you submit your application July 2, 2016, you will have until July 2, 2017 to complete your exam. After this time, applicants must submit a new application and full fee to sit for the exam.
