What the two subtests cover
By the frameworks at oh.nesinc.com, read October 12, 2026, Subtest I (046) is a single domain, Nature of Technology. Subtest II (047), The Designed World, weighs Power, Energy and Transportation 33%, Information and Communication 33%, and Manufacturing and Construction 34%. The split here, 18 questions to 30, follows the real 45 to 75.
The written assignments
Each subtest also sets three constructed-response assignments, 30% of its score, beside multiple-choice questions worth 70%. This page practices the multiple-choice part only.
Timing
A subtest allows 2 hours 30 minutes for its questions and assignments together. No time is published for the multiple-choice part alone, so the exam here runs without a clock.
Subtest I has only 45 questions, but its extended assignment alone is 10% of the score, so leave time to plan it.
Questions and answers
Is this OAE Technology Education practice test free?
Yes, free and with no account. The 48 questions were written for this site from the two published frameworks, each explanation names a public page, and nothing is copied from the real subtests or their sample questions.
How many questions are on OAE Technology Education?
Subtest I (046) has 45 multiple-choice questions and three constructed-response assignments. Subtest II (047) has 75 multiple-choice questions and three assignments.
What is the passing score for OAE 046 and 047?
220. Scores run from 100 to 300, and on these subtests the multiple-choice score is combined with the constructed-response score. The test page says a candidate has to take both subtests and pass both.
Can I take the OAE Technology Education test online?
The test page lists computer-based testing at test centers only, by appointment during testing windows. One subtest or both may be taken at a single appointment.
Which Ohio license needs OAE Technology Education?
The program's table lists Technology Education (046/047) for the Technology Education license under Career-Technical Baccalaureate (4–12), together with an Assessment of Professional Knowledge, 002 or 003.
