The Passing Score: What 220 Actually Means
If you're preparing for the Ohio Assessments for Educators: Foundations of Reading (190), the single most important number to understand is 220. That's the scaled score you need to reach or exceed to pass this Ohio licensure assessment, administered by Evaluation Systems of Pearson on behalf of the State Board of Education of Ohio.
The 220 threshold isn't a raw percentage of questions answered correctly. It's a scaled score derived from your performance across the multiple-choice section and the two written assignments, weighted according to the exam's domain structure. This distinction matters because it means not every question is worth the same amount toward your final result, and some items you encounter may be unscored field-test questions that don't count toward your score at all - a detail worth knowing since Field 190 launched in January 2023 and continues to evaluate new content for future forms.
How the OAE Foundations of Reading (190) Is Scored
The exam combines two very different question formats into one scaled score: 100 multiple-choice questions and 2 written assignments, all completed within a 4-hour testing window. You can take the test either at an official test center or through online proctoring, depending on what's most convenient and available in your area.
Because the multiple-choice and written components are scored differently and then combined, a weak performance on the written assignments can pull down an otherwise strong multiple-choice showing, and vice versa. This is one of the biggest misconceptions candidates have - many assume the multiple-choice section alone determines their fate, then are surprised by how much the written responses influence the final scaled result.
For a deeper breakdown of exactly how difficult each component tends to be for candidates, see How Hard Is the OAE Exam? Complete Difficulty Guide 2026, which walks through where most test-takers lose points.
Domain Weighting and Why It Matters for Your Score
Your scaled score of 220 is built from performance across four content domains, and they are not weighted equally. Understanding this weighting is the single best lever you have for score improvement, because it tells you exactly where to invest your limited study hours.
Domain 1: Foundations of Reading Development (35%)
This is the largest domain on the exam by a significant margin, covering phonemic awareness, phonics, print concepts, and the early building blocks of literacy acquisition. Because it represents over a third of your score, weak preparation here has an outsized effect on whether you clear 220.
- Phonological and phonemic awareness progressions
- Systematic phonics instruction and decoding strategies
- Concepts of print and alphabetic principle
Domain 2: Development of Reading Comprehension (27%)
The second-largest domain focuses on vocabulary development, text comprehension strategies, and how comprehension skills evolve from emergent to fluent readers.
- Vocabulary instruction methods across grade levels
- Comprehension strategies for narrative and informational text
- Fluency's relationship to comprehension
Domain 3: Reading Assessment and Instruction (18%)
This domain tests your ability to interpret assessment data and match instructional decisions to student needs.
- Formal and informal assessment interpretation
- Differentiated instruction based on assessment results
- Progress monitoring approaches
Domain 4: Integration of Knowledge and Understanding (20%)
This domain is assessed primarily through the written assignments, requiring you to synthesize knowledge from the other three domains into applied, constructed responses.
- Case-study style analysis of student reading behaviors
- Justifying instructional recommendations with evidence
- Connecting theory to classroom practice
For the complete, detailed walkthrough of every subskill within each domain, read OAE Exam Domains 2026: Complete Guide to All 4 Content Areas. Since Foundations of Reading Development alone accounts for over a third of your score, it deserves proportionally more study time than any other single domain.
Key Takeaway
Allocate your study hours roughly in proportion to domain weight: Foundations of Reading Development and Development of Reading Comprehension together make up 62% of the exam, so more than half your prep time should live there.
The Two Written Assignments: A Hidden Score Factor
Many candidates underestimate the written assignments because they're used to multiple-choice-heavy licensure tests. On the Foundations of Reading (190), the written portion is where Domain 4 - Integration of Knowledge and Understanding - is primarily assessed, and it's also where general knowledge from the other domains gets applied in a scenario-based format.
To score well on the written assignments toward reaching 220, your responses need to:
- Directly answer the prompt with a clear, defensible position
- Reference specific reading development concepts by name (not vague generalities)
- Connect an instructional recommendation back to evidence from a described student scenario
- Stay organized and complete within the allotted time inside the 4-hour session
Practicing timed written responses - not just multiple-choice drilling - is essential. A comprehensive walkthrough of how to structure your written responses under time pressure is available in OAE Study Guide 2026: How to Pass on Your First Attempt.
What the 69% Pass Rate Tells You
The 2023-24 initial-attempt pass rate for this exam was 69%. That means roughly three out of ten first-time candidates did not reach the 220 scaled score threshold on their first try. This isn't a reason for panic, but it is a signal that the exam rewards structured preparation rather than passive review of general reading education knowledge.
A pass rate in this range typically reflects a mix of candidates: those who treat the exam as a formality after a full teacher-preparation program, and those who underestimate the depth of phonics and phonemic-awareness content in Domain 1. For a full breakdown of pass-rate trends and what factors correlate with first-attempt success, see OAE Pass Rate 2026: What the Data Shows.
Building a Score-Focused Study Plan
Rather than studying generically, structure your preparation around the domain weights and the two-part test format. A focused multi-week plan tied specifically to this exam's structure looks like this:
Foundations of Reading Development
- Deep review of phonemic awareness stages and phonics scope-and-sequence
- Practice multiple-choice items targeting decoding and print concepts
Development of Reading Comprehension
- Study vocabulary instruction models and comprehension strategy frameworks
- Draft short written responses connecting comprehension theory to instruction
Reading Assessment and Instruction
- Practice interpreting sample assessment data and matching interventions
- Review formal vs. informal assessment tools
Integration and Written Assignments
- Full timed practice of both written assignments
- Review Domain 4 case-study scenarios end to end
In the final days before your test date, take full-length timed practice sessions on our practice test platform to simulate the 4-hour format and get comfortable pacing yourself across both the multiple-choice section and the written assignments.
Registration, Fees, and Retake Mechanics
Understanding the practical mechanics around the passing score helps you plan financially and logistically. The exam fee is $139, and you can sit for the test either at an approved test center or via online proctoring - choose whichever format suits your testing preferences and local availability.
Because the exam costs $139 each time you sit for it, falling short of 220 has a real financial cost attached to a retake, not just a delay. This is a strong argument for thorough first-attempt preparation rather than treating the exam as low-stakes practice.

Frequently Asked Questions
You need a scaled score of 220 or higher, based on combined performance across the 100 multiple-choice questions and 2 written assignments.
No. The 220 threshold is a scaled score, not a raw percentage. It accounts for the different formats and weighting of the multiple-choice section and written assignments, so you can't calculate pass/fail by simply counting correct answers.
Foundations of Reading Development, at 35%, is the largest domain and deserves the most study time, followed by Development of Reading Comprehension at 27%.
Yes. The two written assignments are a required part of the exam and are factored into your overall scaled score alongside the multiple-choice section, so weak written performance can prevent you from reaching 220.
You would need to register again and pay the $139 fee to retake the exam. Given the 69% initial-attempt pass rate, thorough preparation before your first sitting is the most cost-effective approach.
