,Q1. A district mandates that all teachers use a common end-of-unit assessment. A
teacher notices that English learners and students with IEPs consistently score lower.
Which action best aligns with assessment fairness and differentiation principles?
A. Provide the assessment in the student's native language or with approved
accommodations
B. Exempt these students from the assessment and assign alternative projects
C. Analyze item-level data to identify biased questions and adjust instruction
accordingly
D. Lower the passing threshold for these subgroups to reduce failure rates
Correct Answer: C. Analyze item-level data to identify biased questions and adjust
instruction accordingly
Rationale: Fair assessment involves examining data to identify and address bias, then
adjusting instruction or accommodations as needed. Exempting students lowers
expectations, and lowering thresholds misrepresents proficiency. Native language or
accommodations are appropriate only when specified in IEPs or language plans.
Why Wrong:
A - Accommodations must align with documented plans; blanket use without analysis
may not address underlying instructional gaps.
B - Exempting students from common assessments violates the principle of high
expectations for all and may mask learning gaps.
D - Lowering passing thresholds compromises academic standards and does not
improve learning or assessment validity.

Q2. In a classroom using Universal Design for Learning (UDL), which practice best
exemplifies the 'multiple means of engagement' principle?
A. Offering students a choice between writing an essay, creating a video, or giving a
presentation to demonstrate understanding
B. Providing audio recordings of all reading materials to support auditory learners
C. Using a digital platform that allows students to adjust font size and background
color
D. Implementing a points-based reward system for completing assignments on time
Correct Answer: A. Offering students a choice between writing an essay, creating a
video, or giving a presentation to demonstrate understanding
Rationale: Multiple means of engagement focuses on motivating and sustaining interest by
offering choices and autonomy. Providing options for demonstrating understanding
engages students by tapping into their interests and strengths. The other options relate to
multiple means of representation or action/expression.
Page 3
, Why Wrong:
B - Audio recordings are a form of representation, not engagement.
C - Adjusting font size and background color is a representation or accessibility
feature.
D - Reward systems may address engagement but do not reflect UDL's emphasis on
autonomy and authentic choice.
Reference: CAST (2018). Universal Design for Learning Guidelines, Version 2.2
Q3. A teacher uses a pre-assessment and post-assessment to measure growth. Which
metric best accounts for the varying starting points of students?
A. Average gain score (post-test minus pre-test)
B. Percentage of students meeting a fixed proficiency benchmark
C. Effect size using Cohen's d with pooled standard deviation
D. Percentage of students showing any improvement
Correct Answer: C. Effect size using Cohen's d with pooled standard deviation
Rationale: Effect size (Cohen's d) standardizes the gain relative to variability, allowing
fair comparison across diverse starting points. Average gain may be skewed by outliers,
fixed benchmarks ignore growth, and any improvement is a low bar.
Why Wrong:
A - Average gain does not account for variability or regression to the mean, making it
less robust.
B - Fixed benchmarks do not reflect growth, especially for students starting below or
above the benchmark.
D - Any improvement is too lenient and does not measure magnitude of change.
Reference: Hattie, J. (2009). Visible Learning, Ch. 2
Q4. Which assessment practice best supports formative assessment's goal of
improving learning during instruction?
A. Administering a comprehensive midterm exam worth 30% of the final grade
B. Using exit tickets to gauge understanding and adjusting the next day's lesson
accordingly
C. Having students grade each other's quizzes without teacher review
D. Providing a detailed rubric after the final project is submitted
Correct Answer: B. Using exit tickets to gauge understanding and adjusting the next
day's lesson accordingly
Rationale: Formative assessment is embedded in instruction to provide ongoing feedback
and adjust teaching. Exit tickets offer immediate data for instructional decisions. Midterms
are summative, peer grading without review lacks validity, and post-submission rubrics
are summative feedback.
