The EPA recommends substantial preparation before taking any of the EPA tests. Many services offer test-taking strategies, practice and preparatory materials, which include study manuals, practice videos and audio tapes. When taking the exam, testing resources recommend finding a quiet place with Internet access, where the test taker has minimal distractions. The only EPA test administered online without a proctor is the Type I test. All other tests require testing at a proctored location.
The EPA Type I test limits the work a certified worker is allowed to do, but it is relatively simple to pass. Testing sites recommend reading a study manual and taking several practice tests prior to taking the online exam.
For preparation, the EPA has an overview page that lists the topics covered on each exam. Users access the page by going to the EPA site and clicking on the Ozone Layer Protection home page, then selecting Regulatory Programs. The main site also provides information regarding online testing, exam locations and study tips.
The Esco Institute is one of many online test preparation sites for the EPA exams, and it provides free practice tests and study guides, as well as access to online testing and in-person testing information. EPA Test is another good resource that provides tips and practice material.
