How Does the Year 1 Phonics Check Fit with DIBELS 8th?
One of the first questions we’ve considered is how the Year 1 Phonics Check aligns with what DIBELS already measures.
Both tools examine decoding skills. The Year 1 Phonics Check shows how well students use sound–spelling correspondences and blending to read unfamiliar words—similar to what DIBELS Nonsense Word Fluency (NWF) assesses.
The key differences are in purpose and frequency:
- Phonics Check: A one-off assessment during Year 1
- DIBELS 8th: Ongoing screening and progress monitoring across primary years, allowing teachers to identify risk early and track progress over time
Together, they offer a complementary picture of students’ foundational reading skills.
Following the DIBELS 8th Administration Timeline.
Schools adopting DIBELS have asked if they need to follow the suggested administration schedule exactly or adapt it slightly for school timetables.
Because DIBELS is a standardised and normed measure, sticking closely to the scoring rules and guidelines is essential to ensure valid data. This means it should be administered as closely to the beginning, middle and end of year as practicable. Fortunately, the recommended windows for beginning-, middle-, and end-of-year testing are broad—about three months—giving schools flexibility without compromising results.
Do I Need Other Reading or Assessments?
It's not necessary to use additional tests unless a student is showing risk. Keep in mind that DIBELS is a quick screener so sometimes more information is required prior to implementing an intervention program. For example, you can use the diagnostic tools available with most phonics programs to help place the student into the appropriate unit of your phonics program. The DIBELS progress monitoring forms can then be used to monitor the effectiveness of the intervention. When progress monitoring, you will use the form that corresponds to what is being targeted in the intervention.
Assessing Letter Sounds in the Early Years.
A common question about the early DIBELS measures is how letter sound knowledge is assessed, given that Letter Naming Fluency (LNF) measures letter name recognition rather than sound proficiency.
LNF checks letter name knowledge and relates to Rapid Automatized Naming (RAN), and low performance may indicate risks related to reading fluency. Letter sound knowledge, however, is assessed within Nonsense Word Fluency (NWF), where students must apply sound–spelling correspondences and blending to decode.
Together, these early measures provide a comprehensive look at foundational reading competence.
All of These Questions Are Covered in DIBELS 8th Edition Training.
As we’ve been digging deeper into these questions, we’ve found that all of them are addressed thoroughly in DIBELS 8th Edition training. The training provides:
• A clear understanding of the purpose of each measure
• How and when to administer each assessment
• How to interpret composite scores and individual measures
• How to choose the right progress monitoring tools
• How to align instruction and intervention with the data
Why training helps:
While DIBELS looks simple on the surface, effective use requires consistency and accuracy. Training helps by:
✔ Ensuring fidelity – Teachers learn the correct administration and scoring procedures, which protects data reliability.
✔ Building confidence – Staff know why each measure matters and how to interpret results correctly.
✔ Strengthening MTSS decision-making – Teachers learn to move from data → diagnosis → instruction → monitoring.
✔ Creating whole-school consistency – Everyone uses the same language, the same timelines, and the same expectations.
✔ Reducing assessment overload – Training helps schools identify when DIBELS alone is enough and when further testing is needed.
Ultimately, training accelerates a school’s ability to use DIBELS not just as a testing tool, but as a powerful driver of instruction and intervention.
