- Each subtest (117, 118, 119, 120) requires a scaled score of 220 out of 100-300 to pass.
- 117-120 are four separately registered, separately scored tests totaling 210 questions and 5 hours 30 minutes.
- Subtest 118 Literacy had the lowest 2024-25 initial pass rate (78.3%), making it the top priority for practice questions.
- Retakes are unlimited, but you must wait for your score report plus 30 days between attempts on the same subtest.
The Magic Number: What "Passing" Actually Means
If you're preparing for MTTC Lower Elementary (PK-3) Education, the number that matters most is 220. That's the scaled score you need on each of the four subtests - 117 Professional Knowledge and Skills, 118 Literacy, 119 Mathematics, and 120 Science and Social Studies - to be considered passing. There is no overall composite score across the four tests. Each one stands alone, is scored independently, and must individually clear the 220 threshold.
This matters for how you plan your prep. You can't average a strong 117 score against a weak 118 score. If Literacy comes in under 220, you retake Literacy - full stop. For a broader breakdown of what's tested inside each subtest, the MTTC Exam Domains 2026: Complete Guide to All 11 Content Areas lays out every domain and weight in detail.
Four Subtests, Four Separate Scores
The 117-120 set is really four distinct exams bundled under one field. Each has its own registration, its own fee, its own appointment, and its own 220 passing threshold:
| Subtest | Content | Questions | Time | Passing Score |
|---|---|---|---|---|
| 117 | Professional Knowledge and Skills | 50 | 1 hr 15 min | 220 |
| 118 | Literacy | 50 | 1 hr 15 min | 220 |
| 119 | Mathematics | 50 | 1 hr 30 min | 220 |
| 120 | Science and Social Studies | 60 | 1 hr 30 min | 220 |
Sit for all four and you're looking at 210 total questions across 5 hours 30 minutes of testing time - plus a separate 15-minute tutorial and nondisclosure agreement at each individual appointment. Remember that the ZO Lower Elementary endorsement technically only requires 118, 119, and 120 plus either 117 or 121, so taking all four is a common path but not the only valid one. If you're unsure which combination applies to your situation, check MTTC Requirements 2026: Eligibility, Prerequisites & How to Qualify before you register.
How the 100-300 Scaled Score Works
Every subtest uses a scaled score range of 100 to 300, with 220 as the cut score. This scaling process converts your raw number of correct answers into a standardized score, which accounts for slight difficulty differences between test forms and any unscored field-test items mixed into your exam. You won't know which items are field-tested and which count toward your score, so the safest approach is to treat every question on the screen as if it counts.
Because the scale runs from 100-300 rather than a percentage, don't try to reverse-engineer "how many questions can I miss" math from outside sources - that kind of estimate varies by form and isn't published by the Michigan Department of Education or Pearson. Focus instead on mastering the content domains directly, since that's the only lever you actually control.
Key Takeaway
Don't obsess over converting 220 into a raw percentage. Scaled scoring accounts for form difficulty and field-test items you can't identify - study every domain thoroughly instead of gaming a percentage target.
Why Domain Weighting Matters More Than You Think
Since each subtest is pass/fail on its own, understanding how domains are weighted inside that subtest tells you exactly where to spend your prep hours. A few examples:
Subtest 1 - Professional Knowledge and Skills
Split between two domains: Learner-Centered Supports carries 60% of the weight, while Professional Knowledge and Strategic Partnerships carries 40%. Because Learner-Centered Supports dominates the subtest, prioritize instructional strategies, classroom environment, and student support scenarios over pure policy knowledge.
- Expect scenario-based questions on differentiating instruction for PK-3 learners
- Know how to interpret collaboration with families and specialists
Subtest 2 - Literacy
Three domains split the weight: Literacy in Context (30%), Literacy Skills-Instruction and Practices (30%), and Literacy Processes-Instruction and Practices (40%). Because Literacy Processes carries the largest single share and this subtest posted the lowest pass rate in 2024-25, it deserves the most concentrated review time of any domain in the entire 117-120 set.
- Phonemic awareness and decoding instruction sequencing
- Comprehension strategy instruction across PK-3 developmental stages
Subtest 3 - Mathematics
Mathematics-Specific Teaching Practices carries 20%, while two Mathematical Knowledge for Teaching domains - Attribution and Counting/Whole Number Representation, and Early Fraction Representation/Whole Number Operation - each carry 40%. Together those two content-knowledge domains make up 80% of the subtest, so pedagogy alone won't carry you here; you need the underlying math content cold. Also remember: calculators are prohibited on subtest 119.
- Number sense progressions from counting to early operations
- Concrete-representational-abstract models for fractions
Subtest 4 - Science and Social Studies
Social Studies Instruction and Practices alone carries 50% of this subtest, with the two science domains - 3-Dimensional Science Learning and Children's Sense-making/Science Teaching Pedagogy - splitting the remaining half at 25% each. Since Social Studies is worth as much as both science domains combined, don't shortchange civics, geography, and history pedagogy while over-preparing the NRC science framework.
- Practices, crosscutting concepts, and core ideas from the science framework
- Instructional sequencing for integrated social studies units in early grades

What the 2024-25 Pass Rates Tell You About Difficulty
Official initial and cumulative pass rates from 2024-25 give a real signal of where candidates struggle:
| Subtest | Initial Pass Rate | Cumulative Pass Rate |
|---|---|---|
| 117 Professional Knowledge and Skills | 95.8% | 97.1% |
| 118 Literacy | 78.3% | 87.6% |
| 119 Mathematics | 81.9% | 89.6% |
| 120 Science and Social Studies | 92.2% | 95.6% |
Literacy is clearly the toughest hurdle on a first attempt, followed by Mathematics. Both subtests still see most candidates pass eventually (cumulative rates climb well above 87%), but the gap between initial and cumulative numbers tells you a meaningful share of test-takers need a second attempt on these two. That's exactly why 118 deserves the most practice-question repetition of any subtest in your prep plan. For a deeper dive into these numbers and what they mean for your own odds, read MTTC Pass Rate 2026: What the Data Shows, and for an overall difficulty assessment across all four subtests, see How Hard Is the MTTC Exam? Complete Difficulty Guide 2026.
If You Don't Hit 220: Retake Rules and Timing
Missing 220 on a subtest isn't the end of your certification timeline, but it does cost you time. Here's exactly how retakes work:
- Retakes are unlimited for any subtest you haven't yet passed.
- You must wait for your official score report before scheduling a retake.
- A mandatory 30-day waiting period applies between attempts on the same subtest.
- Scores are released within six weeks of your test date, so plan retake windows accordingly.
- A passing result on any subtest stays valid for five years, as long as the certificate or endorsement tied to it hasn't been issued yet.
Registration Fees Tied to Each Passing Attempt
Since each subtest is scored and passed independently, each retake also comes with its own fee. Subtests 117, 118, and 119 each cost $59, while 120 costs $69, for a combined $246 if you register for all four at once. If you fail a subtest, you'll pay that subtest's fee again when you retake it - the fees aren't refunded or credited toward a retake. Budgeting for at least one possible retake on 118 or 119, given their initial pass rates, is a realistic way to plan your total spend. A full cost breakdown, including how fees stack up if you need multiple attempts, is available in MTTC Certification Cost 2026: Complete Pricing Breakdown.
Building a Study Plan Around the Passing Score
Because 220 is a fixed bar on every subtest regardless of how "easy" or "hard" the form feels that day, the most reliable strategy is allocating study time proportional to both domain weight and known difficulty. A four-week structure built around the 117-120 set might look like this:
Literacy (118) - Heaviest Investment
- Drill Literacy Processes-Instruction and Practices (40% weight)
- Work full-length practice sets on the main practice test platform to simulate the 50-question, 75-minute format
Mathematics (119) - Content Knowledge Focus
- Master counting/whole number representation and fraction/operation domains (80% combined weight)
- Practice without a calculator, since 119 prohibits one
Science and Social Studies (120)
- Prioritize Social Studies Instruction and Practices (50% weight)
- Review the NRC science framework's practices and crosscutting concepts
Professional Knowledge and Skills (117) and Final Review
- Reinforce Learner-Centered Supports scenarios (60% weight)
- Take timed full-length practice runs across all four subtests to confirm pacing
Notice that Literacy gets the earliest and heaviest slot - that's a direct response to its lower initial pass rate, not a generic recommendation. If you want a more detailed week-by-week breakdown with specific resource types, the MTTC Study Guide 2026: How to Pass on Your First Attempt expands on this approach across all 11 domains. And when you're ready to check your readiness against timed conditions, practice tests built around the actual 117-120 format are the closest thing to a dress rehearsal before test day.
Key Takeaway
Allocate study time by domain weight and known pass-rate difficulty - spend the most hours on Literacy Processes (40% of subtest 118) and the two Mathematics content domains (80% combined) since those are where candidates most often fall short of 220.
Frequently Asked Questions
Yes. Each subtest - 117, 118, 119, and 120 - uses the same 100-300 scaled score range, and 220 is the passing threshold on all four. There's no combined or averaged score across subtests.
No. Numeric scaled scores are only reported for nonpassing results. A passing result is simply reported as a pass, without a specific number attached.
Based on 2024-25 official data, Subtest 118 Literacy had the lowest initial pass rate at 78.3%, followed by Subtest 119 Mathematics at 81.9%. Both subtests still reach cumulative pass rates above 87% once retakes are included.
A passing result on any individual subtest remains valid for five years, as long as the certificate or endorsement it applies to hasn't been issued yet. This gives you flexibility to spread out the four subtests over time.
No. You must wait for your official score report, which is released within six weeks, and then observe a mandatory 30-day waiting period before your next attempt on that same subtest. Retakes themselves are unlimited.
