- ILTS stands for Illinois Licensure Testing System, run by the Illinois State Board of Education.
- Pearson Evaluation Systems administers the exams, including Field 305 and its replacement, Field 702.
- Field 305 costs $110 for 150 questions; Field 702 costs $150 total across six $25 testlets.
- Passing score is 240 for both, but Field 702 also requires meeting the minimum on every testlet.
What Does ILTS Stand For?
ILTS stands for Illinois Licensure Testing System. It is the state-specific set of content examinations that aspiring Illinois educators must pass as part of earning a Professional Educator License (PEL). The acronym doesn't refer to a single test - it refers to the entire testing system, which includes dozens of subject-area exams, one of which is the elementary content assessment this site focuses on: Field 305 (Elementary Education, Grades 1-6) and its incoming replacement, Field 702 (Elementary Education, Grades K-6).
If you've landed here after searching "ILTS," it's worth confirming you're looking at the right credential. Several unrelated certifications share the same three letters, but on this site - and in the context of Illinois teacher licensure - ILTS always means the Illinois Licensure Testing System. For a broader definitional overview, see What Is ILTS? and ILTS Meaning.
Who Runs ILTS and Why It Matters
The Illinois State Board of Education (ISBE) governs the ILTS program - meaning ISBE sets licensure policy, determines which fields are required, and sets passing standards. Pearson Evaluation Systems administers the actual tests: registration, scheduling, delivery at test centers, and scoring. Understanding this split matters practically:
- ISBE decides things like passing scaled scores (240), retirement dates for old fields, and how test results fit into the broader PEL process.
- Pearson decides things like appointment length, test-center logistics, and how preliminary results are delivered on test day.
This distinction explains why a passing score alone doesn't hand you a license. Passing an ILTS content test is one part of the Illinois Professional Educator License process - you'll also navigate other PEL requirements, and notably, edTPA is waived through August 31, 2029, which removes one common licensure hurdle for candidates testing during that window. For a full breakdown of eligibility mechanics, see ILTS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Field 305 vs. Field 702: The Acronym in Practice
The letters "ILTS" cover many individual fields, but the elementary content area is undergoing a transition that every candidate should understand before registering.
| Detail | Field 305 (Grades 1-6) | Field 702 (Grades K-6) |
|---|---|---|
| Status | Retiring summer 2027 | Opened June 29, 2026 |
| Format | Single 150-question exam (120 scorable, 30 non-scorable) | Six separate testlets, 210 questions total |
| Cost | $110 total | $150 total ($25 per testlet) |
| Testing time | 4 hours (4 hr 15 min appointment) | 5 hours 45 minutes total |
| Passing standard | 240 scaled score | 240 cumulative points plus minimum on every testlet |
Because Field 305 has a defined retirement date, candidates planning to test in 2027 or later should default to Field 702 planning. Those testing before the cutoff still have the option to sit for Field 305. Either way, the underlying content - literacy, math, science, social studies, the arts, and physical development/health - remains conceptually similar; what changes is delivery format and fee structure.

Key Takeaway
If you're unsure which field to register for, check the current test-specific retake table and field availability before paying - Field 305 and Field 702 are not interchangeable registrations.
What the "S" Actually Tests: The Six Content Domains
The "System" in ILTS reflects that this isn't a generic teaching-skills exam - it's built around specific, weighted content domains. Whether you take Field 305's single-exam format or Field 702's six testlets, the tested knowledge maps to the same six areas:
Domain 1: Language and Literacy (26%)
The single largest domain. Covers foundational reading skills, literacy instruction methods, and language development for elementary learners.
- Phonemic awareness and early reading strategies
- Literacy assessment and intervention approaches
Domain 2: Mathematics (26%)
Tied with Language and Literacy for the highest weight - together these two domains make up 52% of your score.
- Number sense, operations, and problem-solving pedagogy
- Elementary-level geometry, measurement, and data concepts
Domain 3: Science (13%)
Life, earth/space, and physical science concepts appropriate for elementary instruction.
Domain 4: Social Science (13%)
History, civics, geography, and economics as taught at the elementary level.
Domain 5: Fine Arts (9%)
The smallest domain by weight, covering visual and performing arts instruction basics.
Domain 6: Physical Development and Health (13%)
Movement, wellness, and health education concepts for elementary students.
Notice that Language and Literacy and Mathematics alone account for just over half the total score. That single fact should shape how you allocate study time - it's a much bigger lever than the smaller domains combined. For a full walk-through of each area with sample topics, read ILTS Exam Domains 2026: Complete Guide to All 6 Content Areas.
Format, Fees, and Scoring Behind the Acronym
Understanding what ILTS stands for also means understanding how the "Testing System" actually delivers questions and scores.
- Field 305: $110 registration, 150 total multiple-choice questions (120 count toward your score, 30 are non-scorable field-test items you won't be able to identify), 4 hours of actual testing inside a 4 hour 15 minute appointment window.
- Field 702: $150 total across six testlets at $25 each, 210 questions combined, 5 hours 45 minutes of total testing time. Testlets are administered separately - Foundations of Literacy, English Language Arts and Biliteracy Skills, Mathematics, Science, Social Studies, and Arts, Health, and Physical Development.
- No reference materials are provided in either format - everything you need must be memorized or reasoned through on the spot.
- Preliminary results are issued at the test center, giving you a rough sense of outcome before the official score report posts.
- Passing standard: 240 scaled/cumulative score, with Field 702 adding the requirement of clearing the minimum bar on each individual testlet - you can't offset a weak testlet with a strong one.

Who ILTS Credentials Are For
Passing Field 305 or Field 702 is a requirement for candidates pursuing an Illinois Professional Educator License with an elementary teaching endorsement. This matters for:
- Traditional and alternative-route teacher candidates seeking initial licensure in Illinois
- Out-of-state educators transferring credentials into Illinois's system
- Career-changers entering elementary education who need to demonstrate content mastery
Once licensed, a PEL endorsed in teaching generally renews on a five-year cycle, with $50 in registration fees and a requirement for covered active teachers to complete 120 professional-development hours. In other words, passing ILTS is a gateway, not a one-time event - it plugs into an ongoing licensure cycle.

Turning the Acronym Into a Study Plan
Once you know what ILTS stands for and how its scoring works, the practical question becomes: how do you prepare efficiently? Because Language and Literacy and Mathematics together make up 52% of the score, an effective plan front-loads those domains rather than treating all six equally.
Language and Literacy + Mathematics
- Build a content outline for phonics, literacy instruction, and math pedagogy
- Work through practice items for these two 26%-weighted domains first
Science, Social Science, Physical Development and Health
- Each carries 13% - study them as a group with shared time blocks
- Focus on concepts an elementary teacher would actually deliver in class
Fine Arts + Full Review
- Cover the 9%-weighted Fine Arts domain last, given its smaller share
- Run full-length practice sessions without reference materials, since none are allowed on test day
Whichever field you're registered for, simulate the no-reference-material condition early - it changes how you study far more than most candidates expect. For a complete first-attempt strategy, review ILTS Study Guide 2026: How to Pass on Your First Attempt, and if you want a fast, condensed reference before test day, bookmark ILTS Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Key Takeaway
Weight your study time to match domain weight: Language and Literacy and Mathematics deserve roughly double the attention given to Fine Arts.
