D689: Literacy Assessment and Interventions

Literacy Assessment and Interventions builds the full Tier 1-2-3 MTSS toolkit for diagnosing and closing literacy gaps — including for students with dyslexia.

What D689 covers

The course helps candidates enhance their skills in identifying and addressing literacy challenges in all student populations, including students with dyslexia, through Tier 1, Tier 2, and Tier 3 multi-tiered systems of support and assessment (MTSS). It reviews the science of reading associated with a wide range of assessments and techniques used to evaluate reading, writing, speaking, and listening skills.

A significant focus is on designing and implementing targeted intervention strategies to support student learning in phonemic awareness, phonics, fluency, comprehension, and vocabulary development, with actionable steps to monitor student progress.

The D689 performance assessment

Expect a performance assessment requiring you to interpret literacy assessment data for a given student and design a tiered intervention plan addressing the identified need.

Key topics in D689

• Tier 1, 2, and 3 MTSS
• Literacy assessment administration and interpretation
• Targeted intervention design
• Progress monitoring

Writing tips for D689

Follow the task instructions and rubric line by line

WGU performance assessments for D689 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.

Ground every claim in a specific grade band and student population

Elementary Education courses like D689 typically ask you to design instruction for a specific grade range and set of learner needs rather than write about teaching in the abstract. Evaluators are checking whether your reasoning fits that concrete classroom situation — vague, generic statements about "good teaching" usually lose rubric points for lacking that grade-band specificity.

Because WGU is self-paced, don't let "no deadline pressure" become no submission

There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D689 assessment as a real deadline.

Why students seek help with D689

Candidates sometimes recommend a generic intervention without tying it to the specific assessment data and correct MTSS tier — the rubric typically wants the intervention explicitly justified by the data and matched to the appropriate tier.

How GradeEssays helps with D689

Share your student scenario/data and rubric, and your writer will build a tiered intervention plan explicitly grounded in that data, at the correct MTSS tier.
