D755 prepares special education teachers to use multiple methods of assessment and data sources in making educational decisions about a student and the learning environment.
WGU's guidebook ties it to four uses of data: screening within multitiered systems of support (MTSS), the eligibility process, evaluation, and progress monitoring with data-based instructional decisions.
The challenge is less the vocabulary than the interpretation. You are expected to read a set of scores, explain what they do and do not show, and turn them into a decision that a parent could follow. That takes plain-language writing as much as measurement knowledge.

What D755 Covers
| Competency (WGU wording, summarized) | What you do |
|---|---|
| Analyses data sources to inform selection and development of formal, informal and standardized measures | Choose suitable tools for a student with a possible exceptionality and justify the choice |
| Communicates evaluation results related to measurable outcomes | Explain findings in clear language, with outcomes that can be measured |
| Interprets assessment results to inform educational decisions | Move from scores to eligibility, goals and instructional next steps |
Key Concepts Explained
Formal, Informal and Standardized Measures
Standardized tests are given and scored the same way for everyone and allow comparison with a norm group. Informal measures, such as observations, work samples and checklists, give context. Good assessment uses several sources, because no single score describes a student.
Example: A student scores low on a timed reading test. Before drawing a conclusion you check classroom observations, work samples and attendance. If the student reads accurately but slowly, the finding is a fluency need, not a comprehension one, and the plan changes accordingly.
Progress Monitoring
Progress monitoring means measuring the same skill regularly and comparing results with a goal line. Curriculum-based measures such as words read correctly per minute are common examples.
Example: A goal is to move from 40 to 70 words correct per minute in 15 weeks, a gain of 2 words per week. After 6 weeks the student reads 46. Expected progress would be 52, so the data point sits below the goal line. A sound response changes or intensifies the instruction instead of waiting.
Reliability, Validity and Bias
Reliable results are consistent. Valid results measure what they claim to. You should also consider language, culture and disability-related barriers that can distort results.
Typical Assignments and How to Approach Them
The guidebook does not publish task prompts, so these are typical forms, described in general terms.
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Assessment selection | Matching tools to a student and question | State the question first, then justify each tool |
| Data interpretation | Reading scores and trends | Describe the pattern, give possible causes, avoid overclaiming |
| Results summary for families | Communicating clearly | Plain language, measurable outcomes, no unexplained jargon |
| Eligibility reasoning | Using evidence to inform a decision | Link each conclusion to specific data |
A Study Approach by Competency
- Competency 1, selecting measures. Make a chart of assessment types with purpose, strengths and limits.
- Competency 2, communicating results. Practice rewriting a technical result as two sentences a parent could follow.
- Competency 3, decisions. For each data pattern, write the decision it supports and what other evidence you would want.
A Worked Walk-Through of a Data Task
Suppose you are given a student profile: a fourth grader with oral reading fluency well below grade level, good listening comprehension and an attendance record that shows several absences in the autumn. A strong response follows a repeatable sequence.
- State the question. Is the difficulty with word reading, or with understanding?
- List the sources. Fluency probe, comprehension questions, a listening comprehension task, teacher notes and attendance.
- Describe the pattern. Low accuracy on decoding but strong spoken comprehension points to a word-reading need.
- Qualify. Absences may have reduced instruction time, so intervention response should be checked before concluding.
- Recommend. Targeted decoding instruction, weekly probes and a review date.
Notice that the answer never claims a diagnosis. It says what the evidence supports and what is still unknown, which is the professional stance the rubric looks for.
Where Students Get Stuck
- Treating one score as the answer. Triangulate with several sources.
- Vague outcomes. "Improve reading" is not measurable. State the skill, level, condition and timeline.
- Jargon in family-facing text. Define terms or replace them.
- Ignoring bias. Mention language and cultural factors when they apply.
Study Tips for D755
- Keep a glossary of score types and what each does and does not tell you.
- Sketch a goal line by hand for one practice data set.
- Label every table or graph with its purpose in one sentence.
- Mirror rubric language in your headings.

Frequently Asked Questions
Using multiple assessment methods and data sources for screening in MTSS, eligibility, evaluation, progress monitoring and data-based instructional decisions.
They share a title and description. D755 is in the undergraduate guidebook at 3 units and D763 in the master's at 2 units.
The guidebook describes analyzing data and interpreting results. Check your task instructions for what is required.
One that names the skill, the level to reach, the conditions and the timeline, so progress can be checked with data.
Regular measurement of the same skill, compared with a goal line, to decide whether instruction is working.
No. We tutor, prepare custom answers and give feedback. You submit your own work.
