C871 MA, Science Education Teacher Performance Assessment, catalog number EDUC 6264, is the six-CU culminating assessment of the science education master's degree at WGU. The catalog scope is an original research-based curriculum unit demonstrating your ability to design and implement a multi-week standards-based unit. Two words in that sentence carry most of the weight: original, meaning built by you rather than adapted, and implement, meaning taught to real students rather than designed on paper.
A science unit is judged on coherence, not on activities
Science teachers arrive at this assessment with a folder of activities they know work, and the temptation is to arrange them into a unit. That produces exactly the submission reviewers return. A curriculum unit is scored on whether the parts form a coherent arc toward a defined understanding, and a sequence of good activities that do not build on one another has no arc. The question a reviewer holds throughout is simple: what will students understand at the end that they could not understand at the beginning, and where in this unit did that change happen.
Science units carry a further demand that other subjects do not. Current standards frameworks treat science learning as three strands woven together: the disciplinary content, the practices scientists use, and the ideas that cut across sciences such as cause and effect, systems, and patterns. A unit that teaches content and calls a laboratory exercise the practice component has not woven anything. Reviewers look for students doing something recognisably scientific with the content, building models, arguing from evidence, or planning an investigation, rather than confirming a result the teacher already announced.
Then there is assessment coherence. The unit needs a way of knowing whether the intended understanding arrived, and that assessment has to measure the thing the unit was for. A multiple-choice test on vocabulary at the end of a unit built around modelling is an incoherence a reviewer will name immediately, because it reveals that the design and the goal were never actually connected.
Turning the rubric into a unit plan
Open your Course of Study before you design anything. WGU keeps the scoring detail there rather than in the public catalog, and teacher performance assessment rubrics are among the longest on any plan because the deliverable has many parts, each scored separately.
Every aspect is judged on its own against a three-point scale and a score of 2 in each aspect passes the task. There is no averaging and no compensation. On a six-CU assessment this is the structural fact that decides your timeline: a superb unit design with a thin reflection returns just as surely as a weak one, and the reflection is usually written last, in a hurry, at the point when candidates most want to be finished.
The word budget, worked. Assume twelve scored aspects and a submission running near 7,000 words across the unit plan and its supporting sections. Reserve 350 for an overview and 300 for a closing reflection frame, leaving 6,350 across twelve aspects, about 530 each. Then rebalance: the individual lesson plans consume a large share but are largely structured writing, while the research rationale and the analysis of student learning need genuine argument and deserve 800 each. Take those words from the contextual description, which candidates routinely inflate.
Write the assessment before the lessons. Deciding how you will know students understood forces the unit to aim at something, and it prevents the most common structural fault, which is a well-taught unit whose assessment measures something adjacent.
A structure that fits a science curriculum unit
The task directions govern where they specify a structure. Where they leave room, this arrangement keeps the unit coherent and makes each scored aspect easy to locate.
| Section | What belongs in it | How it gets scored |
|---|---|---|
| Context | The school, the class, the prior knowledge students bring and the resources available | Scored for how the design responds to context, not for the description itself |
| Standards and goals | The standards addressed and the understanding students should hold at the end, stated as understanding rather than as coverage | Scored for alignment and for goals that are actually assessable |
| Research rationale | The evidence base for the instructional approach chosen, tied to this content | Scored where research-based design is named; generic pedagogy citations are weak here |
| Assessment plan | Summative and formative measures, with the criteria and the instrument itself | Scored for measuring the stated goal, which is where incoherence surfaces |
| Lesson sequence | Each lesson with its purpose, the science practice involved, and how it builds on the one before | Scored for coherence; a set of activities without a build is the classic return |
| Differentiation | Specific adjustments for identified learner needs in this class | Scored for specificity; a paragraph of general strategies will not meet it |
| Analysis of student learning | What the assessment data showed, by group and for individuals | The section that proves implementation happened rather than design alone |
| Reflection | What you would change, with reasons grounded in the data | Scored directly and routinely underwritten in the final days |
Safety belongs in every laboratory or field lesson whether or not an aspect names it. A science reviewer reads procedures as a supervisor would, and a described investigation with no hazard control, no waste handling and no supervision plan reads as a unit that was written rather than taught.
Evidence craft in a teacher performance assessment
A teacher performance assessment is an evidence document. Reviewers are looking for proof that the unit was designed deliberately, taught to real students, and evaluated honestly.
- Cite science education research for the instructional decisions, not general education research. The literature on argumentation, modelling and inquiry in science is specific and reviewers know it.
- Name the standards precisely, including the document and the code, and show the alignment rather than asserting it.
- Include the actual instruments. The rubric you scored with, the prompt you used and the recording sheet students filled in are stronger evidence than any description of them.
- Report student learning data in a form that shows distribution, not just an average. Reviewers want to see who did not learn as well as who did.
- Anonymise every student reference completely, including in work samples and in any quoted student language.
- Ground differentiation in identified needs from your context section, so the reader can see the chain from need to adjustment.
- Keep quotation minimal, since standards text is heavily reproduced and WGU runs submissions through a similarity check.
The strongest reflections name a specific failure. A lesson that did not work, with a data-based account of why and a concrete change, demonstrates professional judgement far more convincingly than a unit reported as uniformly successful, which reviewers read as unexamined.
What separates Competent from a return
Work is recorded as Competent or Not Competent, with no letter grades and no ordinary grade point average. Aspects are scored independently, so a six-CU performance assessment usually returns for two or three named aspects rather than as a whole.
- Every scored aspect has a visible heading using the rubric's own wording.
- Every lesson states its purpose and its connection to the lesson before it.
- Every assessment measures the understanding the unit was designed to build.
- Every differentiation decision names the specific need it answers.
- Every claim about student learning is supported by data included in the submission.
- Every reflection point names a change and the evidence that prompted it.
Performance assessment work can be revised and resubmitted with no grade penalty, so a return means rewriting rather than reteaching in most cases. The cost is time, and terms run six months at a flat rate, so a culminating assessment that returns twice can absorb the term that was meant to finish the degree.
Our limits on this course are strict and worth stating plainly. We help you design the unit, structure the document and write to the rubric. We do not teach your lessons, produce student work, invent assessment data or write about students we have not met. Where proctored assessments appear elsewhere on your plan they remain yours to sit, and we never ask for portal credentials.
Six mistakes candidates make in C871
- Assembling activities instead of designing a unit. Coherence is the scored quality, and a strong activity set with no build has none of it.
- Treating science practice as a lab day. A confirmation exercise is not students doing science, and reviewers in a science programme distinguish sharply.
- Writing the assessment last. The measure has to come from the goal, and an assessment retrofitted to finished lessons almost always measures the wrong thing.
- Generic differentiation. Naming a strategy category is not differentiation. Naming the student need and the specific adjustment is.
- Omitting safety. A science unit with unmanaged hazards signals a candidate who did not run the lessons.
- Rushing the reflection. It is scored, it is written last, and it is where a good submission most often loses an aspect.
How support works on this course
Send your Course of Study for C871 with the rubric and the task directions. What comes back is a coherence review that tests whether your lesson sequence actually builds toward the stated understanding, an assessment alignment check that catches the measure-mismatch before a reviewer does, a research rationale sourced from science education literature rather than general pedagogy, and an aspect-mapped document plan with the word budget balanced away from context and toward analysis and reflection.
The teaching stays yours. We do not enter classrooms, produce student work or write data. What we do is make sure the design is defensible before you spend a month teaching it, which is where the six competency units in this course are really spent.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
