WGU D755 ASSESSMENT FOR SPECIAL EDUCATION PRACTICE QUESTIONS
2025/2026 QUESTIONS WITH PASSED ANSWERS/NEWEST UPDATE!!
Question 1
An intervention team is using Positive Behavior Interventions and Supports (PBIS) to evaluate
the effectiveness of a school-wide Tier 1 program. Which form of evaluation is most commonly
used as a primary data source for this tool?
A) Standardized IQ test scores
B) Office discipline referrals
C) End-of-year summative math assessments
D) Student portfolios of creative writing
E) Parent interviews regarding home behavior
Correct Answer: B) Office discipline referrals
Rationale: PBIS is a framework for supporting student behavior. Office discipline referrals
(ODRs) provide objective, quantifiable data on the frequency and severity of behavioral
incidents, allowing teams to determine if behavioral interventions are effectively reducing
disruptive actions.
Question 2
A teacher is reviewing pre-referral data for a student who is not progressing in reading. Upon
analysis, the teacher realizes that the reading assessments used were culturally biased against the
student's background. What is the appropriate next step?
A) Immediately refer the student for a full special education evaluation.
B) Continue with the current interventions for another six months.
C) Collect additional pre-referral data using non-biased or alternative assessments.
D) Place the student in a Tier 3 intensive intervention immediately.
E) Ignore the bias and use the average score of the existing assessments.
Correct Answer: C) Collect additional pre-referral data using non-biased or alternative
assessments.
Rationale: When existing data is skewed by bias, it is not a valid representation of the
student's ability. To make an ethical and accurate decision regarding a referral, the team
must gather new data that accurately reflects the student's skills without cultural or
linguistic interference.
Question 3
A student takes the same reading fluency assessment three times over the course of a week. The
scores are 10 words per minute (WPM), 85 WPM, and 32 WPM. The student’s performance on
other classroom tasks has been consistently average. What is the primary psychometric concern
with this specific assessment?
A) Validity
B) Reliability
C) Bias
D) Standardization
, 2
E) Content coverage
Correct Answer: B) Reliability
Rationale: Reliability refers to the consistency of a measure. Because the student's scores
fluctuated wildly (erratic changes) on the same test despite consistent performance
elsewhere, the assessment tool is failing to provide a stable, dependable measurement of the
student's ability.
Question 4
An evaluator uses a mathematics assessment that only tests single-digit addition to determine if a
student has an overall mathematical learning disability. However, the student's primary struggle
is with word problems and geometry. What is the primary area of concern in this scenario?
A) Reliability
B) Bias
C) Validity
D) Inter-rater consistency
E) Practicality
Correct Answer: C) Validity
Rationale: Validity is the extent to which a test measures what it is intended to measure. If
an assessment only focuses on a narrow set of skills (addition) but is used to draw a
conclusion about "overall" performance, it lacks the necessary content validity to support
that conclusion.
Question 5
A student is evaluated using a behavior checklist. When the general education teacher completes
it, the student receives a high score for aggression. When the music teacher completes it, the
student receives a low score. The assessment relies heavily on subjective interpretation. What is
the primary area of concern?
A) Internal validity
B) Reliability
C) Cultural bias
D) Formative feedback
E) Predictive validity
Correct Answer: B) Reliability
Rationale: Specifically, this is an issue of inter-rater reliability. When different evaluators
get significantly different results using the same subjective tool, the data is inconsistent and
therefore unreliable for making formal eligibility decisions.
Question 6
A math assessment includes multiple questions about the scoring rules and player positions of
American football. Students from international backgrounds who are unfamiliar with the sport
consistently miss these items. This is an example of which concept?
, 3
A) Lack of reliability
B) Low internal consistency
C) Bias
D) Formative assessment
E) Criterion-referencing
Correct Answer: C) Bias
Rationale: Bias occurs when a test requires prior knowledge of specific cultural or social
information that is unrelated to the skill being tested (math). This unfairly disadvantages
students based on their cultural background rather than their academic ability.
Question 7
A student consistently scores very high on a standardized test designed to predict success in
algebra. However, in the actual algebra classroom, the student is failing and cannot perform basic
operations. Which concept represents the focus of this scenario?
A) High reliability
B) Validity
C) Standardization
D) Bias
E) Qualitative data
Correct Answer: B) Validity
Rationale: This scenario highlights a lack of predictive validity. If the assessment results
"poorly predict" actual classroom performance in the related area, the test is not a valid
instrument for its intended purpose of forecasting success.
Question 8
Teacher A conducts a behavioral observation and notes significant difficulties with "off-task"
behavior. Teacher B uses the same checklist one week later and notes the issues are "minor." The
checklist uses subjective measures like "often" or "sometimes" without specific definitions. What
is the primary concern?
A) Validity
B) Reliability
C) Content bias
D) Summative evaluation
E) Norm-referencing
Correct Answer: B) Reliability
Rationale: The lack of objective criteria leads to inconsistent results between different
observers (inter-rater reliability) and over time, making the assessment data unstable and
difficult to interpret accurately.
Question 9
A reading comprehension test features several idioms such as "beat around the bush" and "costs
