Sharpen Reading Transforms Foundational Literacy for Struggling Early Learners

Closing early reading gaps—with results in just months

In this 2024/25 study, the progress of 103 young learners using Sharpen Reading digital platform was evaluated.  

Before using Sharpen Reading, the majority of students in this study were reading one or more grade levels below expectation. Traditional supports weren’t enough to accelerate growth and close the gap.

The results show that learners' consistent and structured use of Sharpen Reading helped struggling readers not only catch up but often exceed their grade‑level targets within months.

The Challenge: Early Learners Falling Behind

Most students in the study began the program reading well below their school grade: 

% of students more than two grade levels behind
80% of Level AA
65% of Level A
45% of Level B1


This reflects a widespread challenge for parents and teachers alike  - how to support foundational reading when kids are falling behind.

The Intervention: Structured, Personalized, and Consistent Instruction

The 103 students in this study received Sharpen Reading instruction to bolster the essential reading skills of decoding, phonemic awareness and fluency.     Outcomes and dosage for the 103 students were analyzed in two subgroups: 

  • Engaged Users ( 67 Students):
    • 4 sessions/week (~16 per month)
    • ~20 min per session, 1 lesson each
    • Fidelity to Sharpen’s adaptive scope/sequence

  • Non‑Engaged Users (37 Students):
    • Inconsistent and/or significantly below dosage guidelines

The Results: Rapid & Significant Reading Growth


Engaged students progressed 1 full grade level in 2–4 months


When Students received Sharpen Reading 5 or more months they improved more than a grade level: 


Beginning Sharpen Level Grade Level Improvement with 5+ months of instruction
Accelerated A 3 grades
Level A 1.6 grades
Level B1 2 grades

Targeted, consistent Sharpen Reading accelerates reading development for students.

What Sharpen’s Formative Assessment Data Shows

Formative assessments of a student's Letter-Sound Knowledge, Spelling, and Word Reading skills were assessed at every other lesson throughout the Sharpen Reading program sequence. Student’s performance on these tasks is evaluated and recorded.  (Note:  Items requiring additional practice are identified and delivered in the curriculum sequence, personalized to each learner through our adaptive learning algorithm)

Formative Assessment data was analyzed in two different ways in order to understand students’ skill mastery and proficiency to gain a comprehensive understanding of student progress. Mastery reflects a higher level of consistency and confidence in applying the core reading skills, indicating that a student has firmly grasped the concept and can use it reliably. Proficiency, on the other hand, serves as an early indicator of learning and shows that a student is beginning to understand and apply the skill but may still need additional practice to reach full mastery. Tracking both measures allows us to identify if and where students differ on skill acquisition and also allows us to recognize early signs of progress. 

Letter-Sounds:
Letter-sound knowledge is one of the core foundational skills of reading. It involves being able to blend letter sounds together to form words. This skill is crucial for decoding unfamiliar words and allowing students to read new texts independently. Our data showed that Engaged users demonstrated letter-sound mastery and proficiency rates nearly double the rate of Non-Engaged users.In other words, Engaged users not only learned letter sounds but were able to more consistently apply this knowledge with accuracy compared to the Non-Engaged Users.

Spelling:
Spelling reinforces reading skills by strengthening knowledge of letter patterns which in turn improves decoding and word recognition abilities. As students become more proficient spellers, they become better equipped to read more complex texts. Our data showed that Engaged users achieved mastery and proficiency rates almost three times the rate of Non-Engaged users Engaged users made significantly greater gains in their ability to recognize and apply spelling patterns compared to Non-Engaged users.

Word Reading:
Word reading is a fundamental skill in the process of learning to read, as it involves the ability to accurately decode and recognize words. This skill is essential because it serves as the foundation for reading fluency, which is the ability to read text quickly, smoothly, and with minimal errors. When students can read words effortlessly, they free up cognitive resources to focus on understanding the meaning of the text, which leads to better comprehension. Our data showed that Engaged users performed more than twice as well as Non-Engaged users in word reading tasks This once again highlights the substantial impact that regular, intensive use of the program has on developing essential reading skills.

Overall, Sharpen’s Formative Assessment outcomes show that sustained and active participation in our program significantly enhances students' abilities to master key literacy skills.
