5.4 Testing Accommodations and Universal Supports for ELLs

Standardized testing policies mandate that English Language Learners (ELLs) participate in state and national accountability assessments. To ensure that these assessments yield valid and fair scores, educators must implement appropriate testing accommodations and universal design supports. The fundamental objective of an accommodation is to level the playing field by removing construct-irrelevant linguistic barriers without giving the student an unfair advantage or altering the target construct measured.

1. Categories of Standardized Accommodations for ELLs

Accommodations are changes in test administration environment, timing, format, or response mode. State policies typically organize accommodations into four primary categories:

                             ┌── Presentation Accommodations (Oral read-aloud, simplified directions)
                             │
Standardized Accommodations ─┼── Response Accommodations (Oral response, pointing, bilingual dictionary)
                             │
                             ├── Timing/Scheduling (Extended time, extra breaks, multi-day testing)
                             │
                             └── Setting Accommodations (Small group, individual, quiet room)

1. Presentation Accommodations

• Oral Reading of Directions / Test Items: Directions read aloud in English or L1. For content tests (e.g., math or science), test items may be read aloud; however, reading test items aloud on a reading comprehension test invalidates the construct (decoding/reading).
• Simplified Language Instructions: Standardized test directions are simplified syntactically without altering test item prompts.
• Visual Scaffolds & Magnification: Providing high-contrast formatting, enlarged text, or visual graphic supports.

2. Response Accommodations

• Bilingual Dictionaries and Glossaries: Providing word-for-word, non-definitional L1-L2 glossaries. These references translate vocabulary directly without providing definitions, explanations, or formulaic examples.
• Alternative Response Modes: Allowing students to point, dictate responses to a scribe, or record oral answers in place of written prose on non-writing tests.

3. Timing and Scheduling Accommodations

• Extended Time: Granting extra time (e.g., 1.5x or 2x standard time) to process text and translate between L1 and L2 mental grammars.
• Frequent Breaks & Multi-Day Testing: Chunking testing sessions over multiple days to prevent cognitive fatigue.

4. Setting Accommodations

• Small Group or Individual Administration: Administering tests in a quiet room or small group setting with a familiar ESOL educator to reduce test anxiety.

2. Validity Considerations of Accommodations

An accommodation is psychometrically valid only if it adheres to the Principle of Differential Boost. This principle states that an effective accommodation significantly improves performance for ELLs (by removing language barriers) but does not improve performance for native English speakers who do not need the support.

[Valid Accommodation Scenario]
ELL Student: Score increases significantly (Language barrier removed)
Native English Student: Score remains unchanged (Construct un-altered)
-> VALID: Removes construct-irrelevant variance without altering target construct.

[Invalid Accommodation Scenario]
ELL Student: Score increases
Native English Student: Score increases significantly (e.g., providing answer keys/hints)
-> INVALID: Alters the core construct and provides unfair advantage.

Instructional Alignment Rule

Testing accommodations cannot be introduced for the first time on the day of a high-stakes assessment. Federal and state guidelines mandate that testing accommodations must align with supports used routinely during daily classroom instruction.

3. Native Language (L1) Assessment Options

Administering content-area assessments in an ELL's native language (e.g., offering a Spanish-language algebra exam) is a highly effective method for isolating content knowledge from L2 proficiency.

Translation vs. Transadaptation

• Direct (Literal) Translation: Translating test items word-for-word from English into L1. This approach frequently fails because literal translations can introduce unnatural syntax, confusing idioms, or altered difficulty levels in L1.
• Transadaptation: A culturally and linguistically sensitive process where test items are adapted into L1 to preserve the original construct, difficulty level, cognitive depth, and cultural equivalence, rather than translating literally.

Prerequisite for L1 Assessment

Native language testing is only valid if the student possesses L1 literacy skills and has received content instruction in L1. Administering a Spanish math exam to an ELL who speaks Spanish orally but attended school exclusively in English or lacks L1 literacy yields invalid results.

4. Universal Design for Assessment (UD-A)

Universal Design for Assessment (UD-A) applies Universal Design for Learning (UDL) principles to test development. Rather than creating a rigid test and retrofitting accommodations after the fact, UD-A designs assessments from inception to be accessible to the widest possible range of learners.
