English Skills Diagnostic
Know Where You Stand. Know Where to Grow.
Every learner has different strengths and areas where they can improve. Students who purchase a lesson package are invited to complete an English Skills Diagnostic with Zach.
This multiple-choice assessment helps identify where focused instruction can help most. It isn’t a pass-or-fail test—it gives us a starting point for lessons built around you.
After 20 completed lessons, you can take the diagnostic again to measure your progress and see how far you’ve come.
