In addition to Driver's Ed, you're required to complete 20 hours of behind-the-wheel supervised driving during your permit phase before getting your intermediate driver's license. This must include at least 2 hours of driving practice between sunset and sunrise. Your supervising driver must log your hours on the driving log located in the parent driving guide.
Note that once you get your intermediate driver's license, you'll need to complete an additional 10 hours of driving practice.
