Overview 

During the 2023–2024 academic year, Lumpkin County Schools in Dahlonega, Georgia, implemented the Reading Horizons® Elevate (RHE) curriculum, which features the Reading Horizons® (RH) method based on the science of reading, with 272 students in grades 4–5.

Lumpkin County Schools, Reading Horizons®, and LearnPlatform by Instructure collaborated to evaluate the impact of RHE usage on NWEA MAP achievement scores (published by Northwest Evaluation Association).

Overview 

During the 2022–2023 school year, Beaufort County Public Schools implemented the Reading Horizons Discovery® curriculum across 84 K–3 classrooms.

Participation in RH Discovery-facilitated professional learning was statistically significant in kindergarten and second grades, such that teachers who completed more RH Discovery-facilitated professional learning had higher spring mCLASS achievement. Similar relationships were found for self-paced professional learning in kindergarten classrooms, such that greater participation in self-paced professional learning was associated with greater mCLASS achievement in kindergarten, greater phonemic awareness in first grade, and greater decoding in second grade. In kindergarten, teachers who had an observation score of 3 or higher had students with statistically significantly higher spring phonemic awareness scores.

Overview 

During the 2022–2023 school year, Council Rock School District in Newtown, PA implemented the Reading Horizons Discovery® curriculum with 718 students across 30 K–2 classrooms.

In first-grade classrooms, more teacher participation in Reading Horizons-facilitated professional learning was statistically significantly associated with higher scores in DIBELS composite, phonemic awareness, correct letter sounds, and words decoded correctly. Kindergarten students in classrooms where teachers completed more self-paced online professional development had significantly higher scores in spring DIBELS composite, phonemic awareness, correct letter sounds, and words decoded correctly.

Overview 

During the 2021–2022 school year, Oklahoma City Public Schools implemented the Reading Horizons Discovery® curriculum across 155 K–4 classrooms.

The RH method’s implementation integrity, as measured by the classroom observation scores on the RHIIR, was statistically significant and showed small to large effects (Cohen’s d ranged from .445 to .944) on outcomes for all grades, controlling for demographics. Substantial effects of observer ratings on decoding scores over time were identified for kindergarten students.

During the 2022–2023 school year, Greenville County Schools in Greenville, SC implemented the Reading Horizons Discovery® curriculum with 1,524 students across 57 kindergarten classrooms.
Statistically significant moderate effects of implementation level were identified for the FastBridge Early Reading Composite Score (d = .22), Decodable Words (d = .25), and Letter Sounds (d = .21).

Overview 

During the 2022–2023 academic year, Anderson County Schools in South Carolina implemented the Reading Horizons Discovery® curriculum with 268 students across 35 K–2 classrooms.

Researchers examined relationships between school-wide implementation and spring NWEA MAP Fluency scores. All relationships were positive and statistically significant, indicating that schools with a greater percentage of teachers using all Reading Horizons practices had higher Phonological Awareness, Phonics Word Recognition, and Language Comprehension scores.

Overview 

During the 2021–2022 academic year, Cleveland County collaborated with Reading Horizons (RH) to study the implementation of RH and explore the relationship between the implementation of the RH method and student learning outcomes in grades K–3. In all analyses, student performance outcomes increased from pre-test to post-test.
