Assessment Accommodations for English Language Learners in Arizona: What Actually Happens
The process is governed by the Arizona Department of Education and tied directly to the ELPA21 assessment system. If you're a test coordinator or an ESL teacher trying to figure out what to put on a student's accommodation sheet, the actual document you need is the Arizona ELPA21 Accommodations Matrix. It breaks everything down by proficiency level and assessment type. The real question most people have isn't about which accommodations exist—it's about which ones are actually valid when you mix ELL designation with other disability designations. Arizona recognizes a specific set of standard accommodations for ELLs taking state assessments. These are not the same as the accommodations you might find in a student's IEP or 504 plan, though there is overlap. The state-mandated standard accommodations include extended time, small group or individual administration, bilingual glossaries for certain subjects, read-aloud provisions for directions and test items (with restrictions on reading passages in math and science), and the use of a word processor or scribe for written responses. There's also the option of administering assessments in the student's native language for the ELPA21 listening and speaking domains under specific conditions. Here's what most people miss: Arizona does not allow translation of the entire assessment into another language for content-area tests like math or science, except in very limited circumstances for newly arrived students within their first year of enrollment. You can use a bilingual dictionary or glossary, but you cannot have a human translate word-for-word during the test. I've seen this violation happen repeatedly at building levels. A teacher brings in a paraprofessional who translates each question aloud, and the resulting score gets flagged during data validation. The workaround is to ensure that any translation support stays strictly within the bounds of the approved glossary list and directional language only.
The proficiency-level gating is another piece that causes real problems in practice. Not every accommodation is available at every ELPA21 proficiency level. For instance, the read-aloud accommodation for test items is typically only permitted for students at the "Emerging" or "Expanding" proficiency levels on the ELPA21 scale, not for those who have reached "Bridging." The Extended Time accommodation, however, is available across all proficiency levels. I spent an entire semester dealing with a district-wide data error where test coordinators had default-set all ELL students to "Emerging" in the assessment platform simply to unlock read-aloud access, even when the students' actual proficiency data showed they were at "Bridging." The fix required pulling the original WIDA screener records, cross-referencing them with the annual ELPA21 scores, and manually correcting each student's profile in the Arizona Assessment Management System. That took about three weeks of full-time work for one person.
The Mechanics of Setting Up Accommodations
The accommodation selection happens inside the Arizona Assessment Management System, often referred to internally as the AMS. You pull up the student's record, navigate to the testing session, and assign accommodations from a dropdown menu. The system will flag conflicts automatically—like when a student has both a scribe accommodation and a read-aloud accommodation selected for the same assessment domain, which creates a logical contradiction that the platform recognizes. One thing that isn't obvious from the official documentation: the difference between an accommodation and a modification in Arizona's framework is procedural, not just semantic. An accommodation changes how a student accesses the test without changing the content being measured. A modification actually changes the content or the performance expectation. Using a translation device that converts passage text into the student's native language is a modification, not an accommodation, and using it on a general state assessment invalidates that student's score entirely. I learned this the hard way with a district that contracted a third-party vendor to provide real-time oral translation services for a cohort of Spanish-speaking ELLs on the Arizona Instrument to Measure Standards (AIMS) math assessment. All of those scores were discarded during the audit phase. The vendor had no visibility into Arizona's accommodation policy boundaries.

What to Watch Out For
The biggest practical bottleneck in Arizona right now is the limited pool of approved native-language assessments. ELPA21 has versions in Spanish, but for students whose primary language is something other than Spanish—Somali, Arabic, Kichwa, Vietnamese—the available accommodations are far more restricted. The state provides directional supports in some of these languages, but you won't find full subject-area bilingual testing options for most languages. If you're working with a significant population of students whose home language falls outside the supported list, your realistic options narrow to extended time, small group administration, visual support, and the use of a bilingual glossary where one exists for the subject area. Another counter-intuitive point: having an IEP or 504 plan does not automatically grant additional accommodations beyond what is already available under the standard ELL accommodations matrix. The IEP team can designate additional supports, but those supports must be documented and tested separately from the standard ELL accommodations. When you're filling out the test session, the ELL accommodations and the disability accommodations come from two different systems that don't always sync cleanly. I've lost count of the number of students who had their disability accommodations overridden because the test session was pulled from the wrong data source. Always verify that both accommodation sets are reflected in the final roster before sending students into the testing environment.
Where to Find the Official Documentation
The primary reference is the Arizona Department of Education's ELPA21 Accommodations Matrix, which is publicly available on the ADE website under the Assessments and Accountability section. It's typically updated annually, usually in the late spring or early summer before the next testing window. You'll also want to keep the Arizona Student Assessment Handbook handy, which covers the intersection of ELL accommodations with disability-related testing supports. The manual is dense and not particularly well-organized, but it contains the policy language that test coordinators rely on during audits. There isn't a single centralized portal that shows real-time accommodation eligibility for every student combination. The AMS dashboard gives you a view of what's currently assigned, but verifying that the assignment matches policy requires manual cross-checking against the proficiency level data and the student's language history. Plan for that. If your building has more than twenty ELL students testing in a given window, budget at least half a day for accommodation verification before the testing session closes.
