At the completion of the course you will be asked to take a written test. This test must be completed and turned in to your local Allan Block sales representative. Once this has been done, the last step is for you to build an Allan Block wall that has a minimum height of 3 ft (0.9 m) and is a minimum of 300 units (full size or equivalent). Notify your local sales representative of the completion of these requirements so that your local sales representative can submit the appropriate paperwork to Allan Block Corp. to receive your Allan Block Certified Wall Installer Certificate.
