Are there tests required? If so, and I fail, will I have an opportunity to take it again?

IBLCE requires that we give a pre-test and post-test in each module. You have one chance to pass each and there are no re-takes. Passing the test is not required in order to successfully complete the module. However, if you fail the post-test, we strongly recommend you re-take the module, to ensure optimal understanding and application of the module/course content. An evaluation is also given and mandatory to receive a certificate and may only be completed once.
