A 6-week HOSA test prep plan

HOSA knowledge tests reward steady preparation more than late cramming. Most of them are short, 50 questions, but they cover a lot of ground, and the guidelines tell you exactly which topics carry the most weight. This plan uses that information to spread six weeks of study across the parts of the test that matter most. It uses Medical Terminology and Behavioral Health as examples, but it works for any HOSA event with a written test.

What do the HOSA guidelines tell you about your test?

Every HOSA event has its own guidelines on hosa.org. For a knowledge test, three parts of that document shape your whole plan.

The format. Medical Terminology and Behavioral Health are both 50 multiple-choice questions in a maximum of 60 minutes. HOSA's written test instructions add a 10-minute buffer and remind you that you're responsible for watching your own time. You bubble answers on an answer sheet with a #2 pencil.

The test plan. This is a breakdown of the test by topic, given as percentages. For 2026-27, the Medical Terminology plan looks like this:

And Behavioral Health:

The references. Each event lists the books and websites its questions are drawn from. Medical Terminology lists Ehrlich's Medical Terminology for Health Professions, Taber's Cyclopedic Medical Dictionary, Stanhope and Turnbull's Introduction to Medical Terminology and Dean Vaughn's Medical Terminology by Body Systems, all in the latest edition.

Behavioral Health lists the SAMHSA and NAMI websites and the textbook Discovering Psychology. You don't need every reference, but you should study from at least one of them.

The tiebreaker. It differs by event, and it decides close results. In 2026-27, Medical Terminology uses two sets of five fill-in-the-blank questions, down from twenty questions last season, and spelling has to be correct. Behavioral Health uses an essay written on the back of the answer sheet.

How do you study for a HOSA test in six weeks?

The plan assumes about 30 minutes a day, five days a week. If your conference is sooner, compress weeks 2 to 4.

Week 1: baseline and setup

• Read your event's guidelines from start to finish, including the dress code and what to bring. For Medical Terminology that's a photo ID and two #2 pencils with erasers (not mechanical).
• Take one timed practice test, 50 questions in 60 minutes, before you study anything. Your score is a starting point, not a verdict.
• Build a study table: each test plan topic, its percentage and your score on it in the practice test.
• Pick your main reference and get access to it through your school library, your adviser or a public library.

Week 2: the biggest section first

Spend this week on whichever topic carries the most weight. For Medical Terminology, that's word parts, nearly half the test.

• Learn 15 to 20 new word parts a day with their meanings.
• Practice breaking terms apart. Take a word such as gastroenteritis and split it into gastr/o (stomach), enter/o (intestine) and -itis (inflammation). Then build new words from parts you know.
• End each day with a 10-question quiz on what you learned, and add every miss to a running list.

For Behavioral Health, start with one of the three 25% sections and outline it from your reference.

Week 3: the next big sections

• Move to the next-largest topics. For Behavioral Health, that's the other two 25% sections. For Medical Terminology, work through the body systems two or three at a time, focusing on terms for anatomy, conditions and procedures.
• Keep reviewing week 2's material for 5 minutes a day, so it doesn't fade while you learn new topics.
• Take a second timed practice test at the end of the week and update your study table.

Week 4: the smaller sections and your weak spots

• Cover the remaining topics. Small sections are still worth points: three 5% sections add up to seven or eight questions.
• Go back to your running list of misses. For each one, write the correct answer and the reason in one line.
• Start tiebreaker practice. For Medical Terminology, practice spelling terms from dictation, because a tiebreaker answer has to be spelled correctly. For Behavioral Health, write one timed practice essay on a topic from the test plan.

Week 5: full practice under test conditions

• Take two full timed practice tests this week, with a pencil and a printed or on-screen answer sheet if you can, in a quiet room.
• Track your pace. Fifty questions in 60 minutes is just over a minute per question, so if you're still on question 20 at the 30-minute mark, practice moving on and coming back.
• After each test, spend as long reviewing as you spent testing. The review is where the score goes up.

Week 6: review and rest

• Use your miss list and your study table to choose what to review. Skip topics you consistently get right.
• Take your last full practice test three or four days before the conference.
• In the last two days, review lightly, sleep normally and pack what the guidelines require.

What should you do on HOSA test day?

• Arrive early with your photo ID and pencils. Earplugs are optional for Medical Terminology; HOSA asks for foam earplugs, not earbuds.
• Fill each bubble completely, and keep track of the clock yourself.
• Answer the tiebreaker questions or essay as instructed.
• Keep what's on the test private afterwards. HOSA's rules say competition details, including test questions, must stay confidential.

What's new in HOSA for 2026-27?

HOSA's update for this season adds new events, including Genetics, Physician Assistant: Medical Case Challenge and Diagnostics by Design: AI in Healthcare, retires Math for Health Care Professions and changes several references and tiebreakers. If you competed last year, reread your event's guidelines instead of relying on what you remember.
