- Subtest 118 Literacy is the hardest of the four, with a 78.3% initial pass rate.
- 117 Professional Knowledge and Skills is the easiest, at 95.8% initial and 97.1% cumulative.
- All four subtests require a scaled score of 220 out of 100-300 to pass.
- Taking 117-120 means 210 questions across 5 hours 30 minutes, plus a 15-minute tutorial each visit.
What Actually Makes This Exam Hard
The honest answer is that "MTTC Lower Elementary (PK-3) Education (117-120)" isn't one exam - it's four independently registered, independently scored subtests, and difficulty varies a lot depending on which one you're looking at. Evaluation Systems/Pearson develops and scores the tests on behalf of the Michigan Department of Education, and the 2024-25 data makes the difficulty gap clear: 117 Professional Knowledge and Skills passed at 95.8% initially, while 118 Literacy passed at just 78.3% initially. That's not a small gap. If you walk into this certification expecting uniform difficulty across all four subtests, you'll misallocate your study time.
This matters because the 117-120 set is also the field's main successor pathway. Elementary Education (103) is being phased out, with its final administration on December 20, 2026, and 103 cannot be used for the ZO or ZP grade-band endorsements going forward. That pushes far more candidates toward 117-120 (or the 118/119/120 + 117-or-121 combination required for the ZO endorsement) than in past years, which is part of why understanding this specific test's difficulty profile - not some other credential that happens to share the "MTTC" acronym - is worth doing carefully.
The Four Separately Scored Subtests
Each subtest has its own registration, fee, time limit, and pass/fail outcome. Understanding the shape of each one before you sit down is half the battle.
| Subtest | Questions | Time | Fee | Initial Pass Rate |
|---|---|---|---|---|
| 117 Professional Knowledge and Skills | 50 | 1 hr 15 min | $59 | 95.8% |
| 118 Literacy | 50 | 1 hr 15 min | $59 | 78.3% |
| 119 Mathematics | 50 | 1 hr 30 min | $59 | 81.9% |
| 120 Science and Social Studies | 60 | 1 hr 30 min | $69 | 92.2% |
Take all four in one plan and you're looking at 210 total questions and 5 hours 30 minutes of actual testing time - plus a separate 15-minute tutorial and nondisclosure agreement segment at every single appointment, since each subtest is booked and administered on its own. Calculators are prohibited on 119, which surprises some candidates who assume a math test would allow one.
For a full breakdown of how each score is calculated and reported, see MTTC Passing Score 2026: Exactly What You Need to Pass.
Domain-by-Domain Difficulty Breakdown
Difficulty isn't evenly spread within a subtest either. Each subtest is built from weighted domains, and knowing the weights tells you where to spend your hours. For the complete framework behind these eleven content areas, see MTTC Exam Domains 2026: Complete Guide to All 11 Content Areas.
Subtest 117 - Learner-Centered Supports (60%)
The largest single domain in the entire 117-120 set. It covers how candidates design instruction around individual learner needs, differentiate for PK-3 developmental stages, and build supportive classroom environments.
- Expect scenario questions about accommodations and developmentally appropriate practice
Subtest 118 - Literacy Processes: Instruction and Practices (40%)
This is the single heaviest domain weight on the hardest subtest - a combination worth respecting. It focuses on how young children develop reading and writing processes and how instruction should scaffold that development.
- Prioritize phonemic awareness, decoding progression, and writing development sequences
Subtest 119 - Mathematical Knowledge for Teaching Grades PK-3 (40% + 40%)
Split across two equally weighted domains - Attribution/Counting and Whole Number Representation, and Early Fraction Representation and Whole Number Operation - these two together make up 80% of the Mathematics subtest.
- Master counting principles, place value models, and early fraction reasoning before touching the 20%-weighted teaching-practices domain
Subtest 120 - Social Studies: Instruction and Practices (50%)
Exactly half of subtest 120 is social studies pedagogy, not science content - a detail many candidates underestimate when they assume this subtest is science-heavy.
- Balance your review time evenly instead of over-indexing on the two 25%-weighted science domains
Key Takeaway
When a single domain carries 40-60% of a subtest's weight, treat it as its own mini-exam during review rather than one bullet point on a checklist.
Why Literacy (118) Trips Up the Most Candidates
With a 78.3% initial pass rate (87.6% cumulative once retakes are factored in), 118 is the clearest outlier among the four subtests - and it's the strongest target for focused practice questions. The subtest is built from three domains: Literacy in Context (30%), Literacy Skills-Instruction and Practices (30%), and Literacy Processes-Instruction and Practices (40%). None of these are trivia domains; they test whether you can apply literacy theory to realistic PK-3 classroom scenarios, which is a very different skill than memorizing definitions.
Candidates who treat 118 the same way they treat 117 - light review, general confidence - are the ones most likely to see a nonpassing score report. If you only have bandwidth to go deep on one subtest before your first attempt, this is the one.
For a wider look at how 118's numbers compare to the other three subtests and what the pass-rate trend suggests about test difficulty over time, read MTTC Pass Rate 2026: What the Data Shows.
Question Format, Timing, and Testing-Day Conditions
All four subtests are computer-based and administered at Pearson VUE test centers. The format itself isn't exotic - multiple-choice questions dominate - but the pacing differs by subtest:
- 117 and 118: 50 questions in 1 hour 15 minutes (about 1.5 minutes per question)
- 119: 50 questions in 1 hour 30 minutes, no calculator allowed
- 120: 60 questions in 1 hour 30 minutes
Every appointment also includes a separate 15-minute tutorial and nondisclosure agreement segment before the clock starts on the actual test - factor that into how much time you block off for testing day. Be aware, too, that any subtest may include unscored field-test items mixed in with scored questions; you won't know which is which, so treat every question as if it counts.
Fees, Retakes, and the 30-Day Waiting Rule
Subtests 117, 118, and 119 each cost $59; subtest 120 costs $69. Registering for all four totals $246. Because each subtest is registered and scored separately, a failed attempt only costs you that one subtest's fee to retake - not the full bundle.
Retakes are unlimited for any subtest you haven't yet passed, but two rules govern timing: you must receive your official score report first, and you must wait a minimum of 30 days between attempts on the same subtest. Scores are typically released within six weeks. A passing result on any given subtest stays valid for five years if the associated certificate or endorsement hasn't been issued yet, so there's no need to retake a subtest you've already cleared just because another one is taking longer.

Who's Actually Hiring for This Certification
The Lower Elementary (PK-3) Education certification lines up with early-elementary classroom roles - kindergarten through third grade, plus pre-K settings - inside Michigan's public and charter school systems. Because Elementary Education (103) is sunsetting for the ZO and ZP endorsements, districts are increasingly looking for candidates who hold the 117-120 (or equivalent 118/119/120 + 117-or-121) combination specifically, which makes this certification path more relevant to hiring pipelines going forward, not less.

Building a Prep Schedule Around the Real Data
Because pass rates differ so sharply by subtest, a flat, evenly distributed study calendar wastes time. A data-informed schedule puts the most hours where the numbers say you need them - heaviest on 118, moderate on 119, lighter on 117 and 120.
118 Literacy - the priority subtest
- Work through all three literacy domains, spending extra time on Literacy Processes-Instruction and Practices (40% weight)
- Use applied, scenario-style practice questions rather than flashcard recall
119 Mathematics
- Drill both PK-3 mathematical-knowledge domains without a calculator
- Rotate in mathematics-specific teaching-practices questions (20% weight) once number-sense content feels solid
120 Science and Social Studies, then 117
- Give real time to Social Studies-Instruction and Practices (50% weight) rather than defaulting to science review
- Finish with 117's Learner-Centered Supports domain, typically the fastest subtest to prepare for
If you want a structured, week-by-week walkthrough of this approach with more detail per domain, see MTTC Study Guide 2026: How to Pass on Your First Attempt. Running timed, full-length questions through our MTTC practice test platform before each subtest is also the most reliable way to confirm you're actually ready rather than just familiar with the material.
Keep your registration dates in mind while you plan - spacing subtests too close together can backfire if the 30-day retake rule ever applies.

Frequently Asked Questions
118 Literacy, with a 78.3% initial pass rate compared to 95.8% for 117, 81.9% for 119, and 92.2% for 120. Its heaviest domain, Literacy Processes-Instruction and Practices, carries 40% of the subtest's weight.
Not necessarily. The Lower Elementary (ZO) endorsement requires 118, 119, and 120 plus either 117 or 121, so taking all four numbered 117-120 is one common route but not the only valid combination.
Each subtest uses a 100-300 scaled score, and you need 220 to pass. A numeric total score is only shown on nonpassing reports.
You must wait for your official score report, which is typically released within six weeks, and then wait a minimum of 30 days before attempting that same subtest again.
No. Calculators are specifically prohibited on 119 Mathematics, and none of the other three subtests permit outside tools either.
Difficulty on this certification isn't a single number - it's four different numbers spread across four differently weighted subtests, and the candidates who prepare with that structure in mind are the ones who clear all of it on the first attempt.
