According to a study conducted by the California Department of Motor Vehicles, home- and computer-based driver's education courses are an effective method to study for the paper DMV exam and are somewhat even more effective than classroom-based instruction and booklets. The study covered the teaching and learning of basic knowledge in early driver's education. Some of the reasons for such greater efficiency may include the lack of distraction from peers, parental influence and self-paced methods.
Students who completed the Internet-based home course in the study performed better in a exit driving test exam than those students who prepared using workbooks and classroom-based courses. Previous recommendations by traffic safety researchers for improving online driver's education included discussions of the benefits of using Internet and interactive technology, keeping students more engaged with the subject and allowing them to retain more material. The California DMV began offering its own online courses and practice tests after releasing the findings of its study.
Those involved in early driver education should be aware that state DMVs regularly supply tests at no cost, although not all of them are online. Even driver's education online companies that charge a fee to provide a certificate for completing a driver's education course generally provide practice tests for free.
