I'm guessing that the one bad review here was written by a teen who clearly didn't like having to take driver's ed. Yes, it's a time-commitment and you have to map it out on your calendar so you don't miss a lesson & have to make it up later, but that's to be expected. Life, as they say, is all about showing up on time.
The program is thorough, and even though it's a tad repetitive, new learners benefit from hearing things more than once! The every other week on-road driving time was the highlight--my teen saw the benefit of that and looked forward to it. I can tell her driving skills improved, and of course got even better as we put in the many hours of road time with her at the wheel.
I recommend this program to everyone who wants to get their license (at any age, but especially the under 18 set) in Oregon. In fact, my teenager pointed out some rules that I didn't know, and I've become a better, more aware driver in the process.
Don't risk letting your teen "wing it"--sign him or her up for this course as soon as your teen is ready to drive.
