D689: Literacy Assessment and Interventions

A study guide to WGU's D689, where elementary education candidates learn to assess reading, interpret the results and plan targeted support.

Updated October 2026 · 5 min read

D689 teaches candidates in WGU's Bachelor of Arts in Elementary Education to find and address literacy difficulties across all student populations, including students with dyslexia.

WGU frames this through Tier 1, Tier 2 and Tier 3 multi-tiered systems of support (MTSS) and the science of reading. The guidebook lists it at 3 competency units.

The course is technical in a different way from maths. You must read assessment data accurately, decide what it says about a child's skills, and match an intervention to that evidence. Students lose marks when their plan sounds sensible but does not follow from the data they presented.

What D689 Covers

Competency (WGU wording, summarized)What it means in practice
Assesses literacy skills through various diagnostic toolsChoosing and administering the right tool for the skill in question
Interprets assessment results to plan interventionsFinding the specific gap and designing support for it
Provides feedback and communication on student progressExplaining results and next steps to students, families and colleagues

WGU's description names the intervention areas: phonemic awareness, phonics, fluency, comprehension and vocabulary.

Key Concepts Explained

Matching Tool to Skill

No single test shows everything. A phonics inventory tells you about letter-sound knowledge; an oral reading record shows fluency and error patterns; a comprehension retell shows understanding. Say why the tool fits the question you are asking.

From Error Pattern to Intervention

Example: A student reads "boat" as "bot" and "rain" as "ran". The pattern suggests difficulty with vowel teams. A Tier 2 small-group plan might teach vowel team patterns explicitly three times a week, using word sorts and decodable text, with progress checked every two weeks. The plan follows directly from the error pattern, which is what evaluators look for.

MTSS Tiers

Tier 1 is core instruction for everyone. Tier 2 adds targeted small-group support for students who need more. Tier 3 is more intensive and individual. Moving between tiers should depend on monitored progress, not on a calendar.

Typical Assignments and How to Approach Them

A Competency-by-Competency Study Approach

  1. Assess. Build a one-page table of five reading skills with a diagnostic tool for each.
  2. Interpret. Practice reading sample results aloud: what is secure, what is not, what is the likely cause?
  3. Communicate. Write one paragraph for a colleague and one for a parent about the same result.

Writing the Interpretation Section

The interpretation is where most marks are earned. A dependable structure uses four short paragraphs in order.

  1. What the data shows. Report results neutrally with figures from the case.
  2. What is secure. Name two skills the child has, with evidence.
  3. What is not yet secure. Name the priority gap and the likely reason, using the error pattern.
  4. What follows. Link the gap to a tier, a strategy and a monitoring plan.

Avoid sentences like "the student struggles with reading". They describe a feeling, not a skill. Prefer "the student reads consonant-vowel-consonant words accurately but reads vowel team words with errors in the vowel sound".

Choosing Between Common Types of Tool

Question you are askingType of toolWhat it tells you
Does the child hear sounds in words?Phonemic awareness taskBlending and segmenting skill
Does the child link letters to sounds?Phonics inventoryWhich patterns are secure
Does reading sound smooth?Timed oral readingRate, accuracy, expression
Does the child understand?Retell or questionsLiteral and inferential understanding

Frequently Asked Questions

What does MTSS stand for?

Multi-tiered systems of support, the framework WGU uses to describe Tier 1, Tier 2 and Tier 3 support.

Does D689 cover dyslexia?

WGU's description says the course addresses literacy challenges in all student populations, including students with dyslexia.

How many competency units is D689?

The BA Elementary Education guidebook lists 3. The MAT guidebook lists the same course at 2.

Which skills do interventions target?

WGU names phonemic awareness, phonics, fluency, comprehension and vocabulary development.

How should I present results?

Strengths first, then the specific gap, then the plan, then how you will monitor progress.

Can you do the assessment plan for me?

No. We tutor and edit your own work. You complete and submit it yourself.
