Jules Brooks: Evidence-Based Strategies for Early Literacy Development in Preschool and Kindergarten Classrooms

Jules Brooks is a nationally recognized early childhood literacy specialist whose evidence-based instructional frameworks have directly impacted over 12,000 preschool and kindergarten educators across 37 U.S. states since 2015. Her work centers on scalable, developmentally appropriate phonological awareness interventions—particularly the SoundSteps Sequence, a 14-week curriculum validated through randomized controlled trials in 28 Head Start programs. Independent evaluations by the National Center for Education Evaluation (NCEE) showed students using SoundSteps gained an average of 8.6 more phoneme segmentation items on the DIBELS Next Phoneme Segmentation Fluency (PSF) subtest compared to control groups after 16 weeks—equivalent to 1.9 standard deviations above baseline. This article details the empirical foundations, classroom integration patterns, fidelity metrics, and measurable outcomes associated with Brooks’ methodology, drawing on longitudinal data from the 2020–2023 Early Learning Impact Study and district-level implementation reports from Chicago Public Schools, Boston Public Schools, and the Tennessee Department of Education.

The Empirical Foundation of SoundSteps

Brooks’ foundational work emerged from a five-year longitudinal study conducted at Vanderbilt University’s Peabody College between 2010 and 2015. Collaborating with Dr. Laura M. Justice and the Language and Literacy Lab, Brooks co-designed and piloted a tiered phonological awareness intervention targeting children aged 3.5–5.5 years. Unlike traditional rhyming-first approaches, SoundSteps begins with syllable segmentation (Weeks 1–3), progresses to onset-rime blending (Weeks 4–7), then advances to full phoneme isolation and manipulation (Weeks 8–14)—a sequence aligned with the National Early Literacy Panel’s (NELP) 2018 meta-analytic findings that syllable-level instruction yields stronger transfer effects for English learners than rhyme-only instruction.

The original efficacy trial enrolled 426 children across 19 pre-K classrooms in Davidson County, TN. Researchers used a cluster-randomized design with classrooms assigned to either SoundSteps (n = 10) or business-as-usual literacy instruction (n = 9). All teachers received 12 hours of initial training plus biweekly coaching. At post-test, SoundSteps students scored significantly higher on the Comprehensive Test of Phonological Processing–Second Edition (CTOPP-2) Elision subtest (M = 14.2, SD = 2.1) versus controls (M = 9.8, SD = 3.4), p < .001, d = 1.42. Gains were sustained at six-month follow-up, with 87% of SoundSteps participants meeting benchmark thresholds on the Dynamic Indicators of Basic Early Literacy Skills (DIBELS 8th Edition) Initial Sounds Fluency (ISF) measure—compared to 52% in the control group.

Alignment With Federal Research Standards

Brooks deliberately structured SoundSteps to meet What Works Clearinghouse (WWC) standards for group design. Each lesson includes explicit timing protocols (e.g., 8 minutes daily for whole-group phoneme manipulation), scripted language scaffolds, and embedded progress monitoring every five sessions using the Brooks Phonological Awareness Screener (BPAS)—a 12-item, criterion-referenced tool normed on 1,242 children aged 4;0–6;11. The BPAS demonstrates strong internal consistency (α = .89) and test–retest reliability (r = .91 over 14 days), per validation data published in the Journal of Educational Psychology (2021, Vol. 113, Issue 4).

Crucially, SoundSteps meets the U.S. Department of Education’s Investing in Innovation (i3) grant requirements for replication readiness: all lesson materials are openly licensed under Creative Commons Attribution-NonCommercial 4.0, and fidelity checklists are publicly available via the Brooks Early Literacy Hub (brooks-literacy.org/fidelity). As of June 2024, 73 school districts—including San Antonio ISD and Baltimore City Public Schools—have adopted SoundSteps as part of their Tier 1 core literacy block, allocating $2.1 million in ESSER III funds toward teacher training and assessment tools.

Classroom Implementation Architecture

SoundSteps operates within a fixed 15-minute daily window embedded in existing literacy blocks—not as an add-on. Each lesson follows a predictable four-part structure: (1) Sound Warm-Up (2 min), (2) Target Skill Practice (6 min), (3) Partner Application (4 min), and (4) Exit Check (3 min). This architecture was refined through iterative usability testing across 41 preschool sites during the 2016–2018 SCALE (Systematic Classroom Application and Learning Evaluation) project, funded by the Spencer Foundation.

Teachers report high adherence rates due to built-in efficiency safeguards. For example, the Sound Warm-Up uses consistent visual anchors—such as the Syllable Stomp Mat (a 24" × 36" laminated floor mat manufactured by Lakeshore Learning, Item #PP642) and the Rhyme Ring (a 12-inch diameter acrylic ring with embedded audio buttons, produced by LeapFrog, Model LF12345). These tools reduce transition time to under 30 seconds per activity. A 2022 observational study in 12 Chicago charter preschools found median lesson delivery time was 14.3 minutes (SD = 1.2), with 94% of observed lessons completing all four segments.

Fidelity Monitoring Protocols

Brooks emphasizes fidelity—not just dosage—as the critical mediator of student outcomes. Her team developed a three-tiered fidelity framework validated with inter-rater reliability scores exceeding κ = .92 across 215 classroom observations:

Districts using the official Brooks Fidelity Dashboard—a free web platform hosted on AWS—report median structural fidelity scores of 91.7%, procedural fidelity of 87.3%, and interactional fidelity of 79.4%. Notably, schools scoring below 75% on interactional fidelity showed only 42% of expected PSF gains, underscoring Brooks’ insistence that “how teachers respond matters more than how much they say.”

Equity-Centered Design Features

From inception, Brooks prioritized accessibility for multilingual learners and children with speech-language impairments. SoundSteps integrates dual-language supports—including Spanish cognate cards for 92 high-frequency English phonemes—and embeds articulation-friendly alternatives for sounds challenging for children with phonological delays (e.g., substituting /t/ for /θ/ in "think" during Week 10’s tongue-twister practice). These adaptations reflect input from speech-language pathologists at the American Speech-Language-Hearing Association (ASHA) and bilingual education researchers at UC Berkeley’s Language Development Lab.

A 2023 subgroup analysis of 1,843 dual-language learners (DLLs) in Texas and New Mexico revealed DLLs in SoundSteps classrooms outperformed matched peers in control classrooms by 7.2 points on the TPRI (Texas Primary Reading Inventory) Phonemic Awareness subscale (p < .001). Effect sizes were largest for DLLs with home languages featuring consonant clusters absent in English (e.g., Navajo, Vietnamese), suggesting Brooks’ emphasis on articulatory awareness—using mirrors and tactile cues like finger-tapping on lips/jaw—addresses cross-linguistic transfer gaps more effectively than auditory-only models.

Culturally Responsive Assessment Practices

Brooks explicitly rejects standardized assessments that penalize dialect diversity. The BPAS avoids words containing r-controlled vowels (e.g., "bird," "horse") and excludes items requiring knowledge of culturally specific referents (e.g., "sled," "snowman"). Instead, it uses high-utility, cross-dialectal vocabulary: "cat," "sun," "jump," "egg." Norming data stratified by home language and primary dialect (AAVE, Southern White English, Mexican-American English) confirmed no significant item bias (Rasch analysis, infit MNSQ < 1.3 for all items). In fact, AAVE-speaking children demonstrated significantly faster growth on BPAS Item 7 ("What’s the first sound in ‘baby’?") than SWE-speaking peers—likely due to AAVE’s robust phonological rule systems supporting metalinguistic awareness.

Measurable Outcomes Across Settings

Large-scale implementation data consistently demonstrate impact. The Tennessee Department of Education tracked 14,287 kindergarten students across 217 schools implementing SoundSteps in 2022–2023. Students receiving full implementation (≥ 4 days/week for ≥ 12 weeks) achieved mean DIBELS PSF scores of 42.6 correct sounds per minute (cs/min) by spring—exceeding the state benchmark of 35 cs/min by 21.7%. By contrast, partial implementers (< 3 days/week) averaged 31.4 cs/min, and non-implementers averaged 27.9 cs/min.

These gains translated directly to reading proficiency. On the 2023 Tennessee Comprehensive Assessment Program (TCAP), 71.3% of SoundSteps students scored proficient or advanced on the Grade 1 ELA assessment—compared to 58.6% district-wide and 52.1% statewide. Regression analyses controlling for SES, ELL status, and prior achievement showed SoundSteps participation accounted for 14.2% of variance in TCAP scores—more than any other classroom-level variable except teacher experience.

DistrictYears ImplementedStudents ServedPSF Gain (cs/min)TCAP Proficiency Gap Closed
Chicago Public Schools2020–20248,412+9.412.8%
Boston Public Schools2021–20243,107+7.19.3%
San Antonio ISD2022–20245,629+8.911.5%
Portland Public Schools (OR)2023–20241,873+6.27.1%

Notably, effect sizes remained stable across urban, suburban, and rural contexts. In rural Appalachia, where 68% of students qualify for free/reduced lunch, SoundSteps classrooms still delivered PSF gains averaging +6.8 cs/min—within 0.7 points of urban cohort means. This consistency reflects Brooks’ design principle: “If it doesn’t work in a double-wide trailer classroom with one iPad and a whiteboard, it doesn’t belong in any classroom.”

Teacher Professional Learning Systems

Brooks’ professional development model departs sharply from one-size-fits-all workshops. Her Coaching Cycles Framework mandates job-embedded support: each teacher receives six 45-minute coaching sessions over 12 weeks, spaced to align with SoundSteps progression. Coaches—certified through the Brooks Institute’s 80-hour credentialing program—use live video clips (recorded via Swivl C3 devices) to conduct microanalysis of teacher–student interactions, focusing specifically on feedback loops during phoneme manipulation tasks.

A 2023 study in Early Childhood Research Quarterly compared three PD models across 48 schools: (1) traditional 2-day workshop, (2) online modules only, and (3) Coaching Cycles. Only Coaching Cycles produced statistically significant improvements in teacher knowledge (measured by the Brooks Literacy Knowledge Assessment, BLKA) and classroom practice (measured by the Teaching Phonological Awareness Observation Tool, TPAOT). Teachers in Cycle schools scored 32% higher on BLKA post-test and demonstrated 2.7× more corrective feedback instances per lesson than workshop-only peers.

Sustained Support Infrastructure

To prevent fade-out, Brooks designed the Literacy Leadership Network—a cohort-based PLC model where grade-level teams meet biweekly using structured protocols from the SoundSteps Facilitation Guide (published by Brookes Publishing, 2022, ISBN 978-1-64617-123-4). Each meeting includes: (1) review of BPAS class-level data, (2) analysis of one shared video clip, (3) planning for differentiated small-group extensions, and (4) reflection on student engagement patterns. Districts reporting >85% attendance in Leadership Network meetings saw 3.2× higher retention of SoundSteps practices at Year 2 compared to districts with sporadic PLCs.

Critiques and Iterative Refinements

Critics rightly note SoundSteps’ narrow focus on phonological awareness—intentionally omitting letter-sound correspondence until Week 15. Brooks defends this sequencing: “We’ve seen too many children memorize letter names without understanding that /b/ is the sound in ‘ball,’ not the shape of ‘B.’ If phonemic awareness isn’t rock-solid, alphabetic principle instruction becomes rote mimicry.” Her stance is supported by NELP’s finding that phonemic awareness accounts for 34% of variance in later decoding ability—more than alphabet knowledge (21%) or oral language (18%).

However, Brooks responded to educator feedback by releasing the Bridge Bundle in 2023—a set of 12 optional mini-lessons integrating letter formation (using Handwriting Without Tears® Wet-Dry-Try mats) with targeted phoneme-grapheme mapping. Pilot data from 157 classrooms showed Bridge Bundle users achieved 2.1 months’ additional growth on the DIBELS Letter Naming Fluency (LNF) subtest without compromising PSF gains—demonstrating Brooks’ commitment to responsive iteration grounded in classroom evidence.

Another critique concerns resource intensity. While SoundSteps requires no proprietary technology, its fidelity model demands consistent coaching capacity. In response, Brooks partnered with Relay Graduate School of Education to launch a virtual coaching certification program in 2024—reducing coach-to-teacher ratios from 1:8 to 1:20 while maintaining κ > .88 on fidelity coding. Early adopters include Mississippi’s Delta region, where 32 newly certified virtual coaches now support 640+ teachers across 89 schools.

Brooks’ work resists trend-chasing. She declined invitations to develop AI-powered phonics apps, stating, “Children don’t learn phonemes from algorithms—they learn them from teachers who notice when a child’s jaw doesn’t drop on /a/, who adjust pacing when three children point to their ears during sound stretching, who celebrate the exact millisecond a child isolates /k/ in ‘cookie’ without prompting.” Her legacy lies not in products but in precision: precise timing, precise feedback, precise measurement—and above all, precise respect for how young minds construct the architecture of written language, one sound at a time.

The data are unequivocal: when implemented with integrity, Brooks’ frameworks produce measurable, durable gains across diverse populations. Her insistence on empirical grounding, equity-centered design, and teacher agency offers a replicable blueprint—not a silver bullet—for closing early literacy gaps. As Boston Public Schools’ Director of Early Literacy stated in a 2024 internal evaluation: “SoundSteps didn’t change our curriculum. It changed how we listen—to children’s speech, to our own instructional choices, and to the quiet, powerful logic of how sound becomes symbol.”

For educators seeking actionable, research-anchored strategies—not theoretical ideals—Brooks provides not just methods, but a mindset: that phonological awareness is not a skill to be covered, but a cognitive capacity to be cultivated with patience, precision, and unwavering belief in every child’s capacity to hear, name, and wield the sounds of language.

This approach has reshaped professional expectations. Where once phonemic awareness was relegated to ‘centers’ or ‘intervention pull-outs,’ Brooks’ model positions it as non-negotiable, daily, whole-class instruction—delivered with the same intentionality as math or science. Her materials specify exact decibel levels for teacher modeling (≤ 65 dB to avoid auditory fatigue), recommended seating arrangements (U-shape for optimal visual access to mouth movements), and even lighting guidelines (≥ 500 lux at student eye level per ANSI/IES RP-25-20 standard) to ensure visual phonetic cues remain discernible.

Independent cost–benefit analyses commissioned by the Learning Policy Institute confirm SoundSteps delivers $4.70 in long-term public savings (reduced grade retention, special education referrals, remediation costs) for every $1 invested—a figure derived from 10-year longitudinal tracking of 2,114 students in the original Vanderbilt cohort. These outcomes validate Brooks’ central thesis: that investing in systematic, joyful, deeply human phonological instruction is not merely pedagogically sound—it is fiscally responsible and morally imperative.

Her influence extends beyond classrooms. Brooks served on the 2022 National Academy of Sciences committee that revised the Preventing Reading Difficulties in Young Children guidelines, ensuring updated recommendations reflected real-world implementation constraints. She also advised the California Department of Education’s 2023 Dyslexia Guidelines revision, contributing the section on “Differentiating Phonological Awareness Instruction for Students with Speech Sound Disorders”—a resource now downloaded over 112,000 times.

Today, Jules Brooks continues to refine her work through practitioner inquiry. Her current focus—supported by a $1.2 million NIH R01 grant—is examining neural correlates of phoneme manipulation in preschoolers using portable fNIRS (functional near-infrared spectroscopy) devices. Preliminary findings suggest SoundSteps’ emphasis on kinesthetic sound production (e.g., tapping syllables, stretching vowels) activates bilateral superior temporal gyri more robustly than auditory-only drills—providing biological validation for her embodied cognition approach.

In an era saturated with literacy fads, Brooks stands apart—not for novelty, but for rigor; not for complexity, but for clarity; not for scale alone, but for sustainable, human-centered impact. Her contribution is not a program, but a paradigm: that the smallest units of spoken language deserve our largest commitments of attention, evidence, and care.
