Switching from UFLI to Fundations mid-year: a migration checklist

Most of the time, the question schools face isn’t whether to switch curricula mid-year. It’s how to land the switch that’s already been decided. A board adoption vote happened in February. The Wilson Fundations kits arrived in March. The professional development is scheduled for spring break. Teachers find out at the staff meeting that they’ll be running a different program in three weeks.

That’s the actual scenario, and it’s far more common than the literature on curriculum adoption suggests. The decision is rarely owned by the people implementing it, and the implementation rarely gets the runway it deserves. The smaller question — should we switch? — has already been answered. The bigger question is how do we land this without losing student progress, teacher morale, or parent confidence?

This is a checklist for that bigger question. It assumes the switch is happening, both curricula are Science-of-Reading-aligned (UFLI Foundations and Wilson Fundations both are), and you have between two and twelve weeks before the first lesson under the new program.

When this switch usually happens

A handful of forcing functions tend to drive a mid-year curriculum change. Recognizing which one is in play helps you prioritize correctly.

A board-level adoption vote. A district committee evaluated programs over the fall, recommended Wilson Fundations, the board voted in late winter, and implementation was scheduled for the back half of the year so the program is “in place” before the next budget cycle. The board owns the timeline; teachers inherit it.
State adoption list compliance. Several state literacy laws require districts to use programs from an approved list, and approval cycles refresh on their own calendar. A district running UFLI Foundations may need to switch to a state-listed program by a specific deadline — or risk losing categorical funding tied to the law.
Prior curriculum sunset or change in publisher support. Less common with UFLI (open-access, maintained by the University of Florida), more common when the prior program was a commercial product whose vendor relationship changed.
Audit findings or intervention identified by the state. A district flagged as not meeting reading benchmarks may be required to adopt a specific listed program as part of a corrective plan.
Building-level realignment. Sometimes one school in a district is switching while others stay on UFLI — usually because Wilson Reading System is already in use for intensive intervention and leadership wants the Tier 1 core from the same publisher family.

The driver matters because it tells you whether you can negotiate the timeline, the scope (all grades or just K-2 first), and which supplementary resources you can keep. A board adoption is harder to flex than a building-level decision.

What doesn’t carry over cleanly: scope and sequence

The single biggest reason mid-year switches are operationally hard is that the two programs don’t share a phonics sequence. They share the same destination, but they take different routes there.

UFLI Foundations begins with single letter-sounds and proceeds to short vowels in CVC words, then digraphs (sh, ch, th, wh, ck), then consonant blends, then silent-e (VCe) patterns, then vowel teams, then r-controlled vowels, and so on. The published manual lays out roughly 128 lessons across the K-2 scope.

Wilson Fundations organizes its sequence around syllable types. Level K introduces consonants and short vowels; Level 1 formalizes “closed syllables” (the consonant-vowel-consonant pattern with a short vowel, terminology Wilson uses explicitly), then introduces digraphs, then short-vowel exceptions, then bonus letters and welded sounds (-ang, -ank, -ong, -ing, -ung, -unk, -onk, etc.). The “syllable type” framing is central to Wilson’s pedagogical lineage in Orton-Gillingham.

A student who’s halfway through UFLI’s vowel-team unit isn’t at an obvious matching point in Wilson Fundations. Wilson may not even introduce some of those patterns at the same grade level. The reverse is also true — a Wilson Level 1 student moved to UFLI may already know patterns UFLI introduces later, but not patterns UFLI introduces earlier.

This is where the gap-analysis work happens, and it’s not optional.

What does carry over: heart words, screening data, decoding habits

Some things travel cleanly across the switch. Don’t waste effort re-teaching them.

Heart words. Both curricula teach high-frequency irregular words using a “what’s regular / what’s irregular” approach (Wilson calls them Trick Words; UFLI uses Heart Words). The actual word lists differ in order but heavily overlap in content. A student who knows said, was, and come in UFLI still knows them after the switch.
Phonemic-awareness fluency. If students have been doing Heggerty alongside UFLI, that work is fully portable. Wilson Fundations embeds more PA inside the main routine (Drill Sounds, Echo Find Letter), but supplementary Heggerty doesn’t hurt.
Universal screener data. DIBELS, Acadience Reading, mCLASS, FastBridge — these are independent of the Tier 1 curriculum. Mid-year scores from before the switch are still valid baseline data after.
Oral reading fluency (ORF) records. WCPM growth is curriculum-agnostic. If you’ve been tracking it, keep tracking it.
General decoding habits. Students who’ve been explicitly taught to sound out words rather than guess from context bring that habit with them. The orthographic mapping skill doesn’t disappear when the lesson order changes.
Foundational concepts. Letter-sound correspondences, syllable awareness, the alphabetic principle — none of this is curriculum-specific.

This list matters because it shapes what teachers should not spend prep time on. The new curriculum will have placement guidance for some of it. Trust it.

Teacher retraining: Wilson requires certified PD

This is the line item most schools underestimate.

UFLI Foundations has no formal certification requirement. The instructional manual is available as a free download, training is self-paced through the University of Florida Literacy Institute, and most districts run their own internal PD using the publicly available materials. Adoption can be done by a coach over a few days of preparation.

Wilson Fundations requires Wilson-certified professional development. The Fundations launch workshop is typically a multi-day institute delivered by a Wilson-credentialed presenter, and the publisher’s recommendation is that every teacher running the program completes that workshop. Some districts add Level-specific follow-up workshops and ongoing coaching cycles.

Three implications for a mid-year switch:

Schedule the PD before the launch. If teachers haven’t been certified, the program won’t be run with fidelity. “We’ll do the training in the summer” is often the right answer; it pushes some of the rollout to fall.
Build coverage for the PD days. If your spring calendar can’t absorb multi-day teacher absences, this is the constraint to flag to the board before the rollout date is set.
Plan for a coaching cycle. Wilson’s published guidance recommends instructional coaching during the first year of implementation. Building this in reduces fidelity drift in months two and three.

Decodable text migration: the hardest part

Here’s the operational problem teachers actually feel: the decodable books on the classroom shelves don’t match the new sequence.

UFLI’s published decodables (and the wider ecosystem of UFLI-aligned decodables — Flyleaf, Pinata, Bob Books revised editions) are organized around UFLI’s lesson order. A book that fits perfectly into UFLI Lesson 47 may use patterns that haven’t been introduced yet in the Wilson sequence at the equivalent grade, or it may be reviewing patterns Wilson hasn’t taught.

Wilson Fundations ships its own leveled decodable readers (Storybooks aligned to each level). They’re high quality and tightly aligned to Wilson’s sequence — but they don’t include the UFLI-style decodables you’ve already invested in.

A few realistic responses:

Run a brief audit. For each decodable on the classroom shelves, ask: does this book’s word list fit inside the cumulative inventory of Wilson Fundations at the grade you’re teaching? Many books will still be usable, but as review reading or independent reading rather than as “today’s lesson decodable.”
Don’t throw out the old books. Even if a book doesn’t match a Wilson lesson, it may still be usable for fluency practice once students have caught up to its patterns under the new sequence. Shelve them by phonics inventory, not by which curriculum they came from.
Use the included Wilson Storybooks for lesson-aligned reading. That’s what they’re designed for.
Bridge with on-demand decodable generation. Several modern platforms can generate decodable text inside a specific phonics inventory. This is one of the few areas where a digital practice layer materially helps — you can ask for a book inside Wilson Step 2.3’s cumulative scope and not have to rummage through a bin to find one.

Assessment continuity

If your prior assessment system was tied to UFLI’s structure, plan the handoff.

Universal screeners (DIBELS, Acadience, mCLASS) keep running. No change.
Curriculum-embedded checks change. Wilson Fundations includes unit checkpoints and Trick Word assessments. UFLI relied more heavily on external screeners. Build the new in-program checkpoints into your data review cadence.
Placement after the switch. Don’t assume the grade-level Wilson scope is the right starting point for every student. Some students will be ahead of where Wilson begins for their grade; others will be behind. Use the unit checkpoints early to calibrate.
Progress monitoring for Tier 2 students. If you have students on intervention, document whether the intervention program is also changing (it usually shouldn’t — Tier 2 programs like Wilson Reading System, SIPPS, REWARDS are independent of the Tier 1 core). Keep the Tier 2 progress-monitoring cadence intact.

Parent communication

The least technical line item, and the one that most often surprises teachers.

Kids’ books on the shelf will change. The homework will look different. The “Heart Word” vocabulary your parent newsletter has been highlighting will be called “Trick Words” next month. The lesson sequence parents had started to internalize is no longer the sequence.

A short parent letter (one page, plain language) goes a long way:

“Our school is moving from UFLI Foundations to Wilson Fundations starting [date].”
“Both programs are Science-of-Reading-aligned. The change in lesson order doesn’t change what we’re teaching — phonics, decoding, and reading comprehension built on a structured sequence.”
“Some terminology will change. The high-frequency words your child was learning as ‘Heart Words’ will be called ‘Trick Words.’ The phonics patterns may be introduced in a different order.”
“Your child’s screening data and reading progress are preserved. Their teacher will share an update at conferences.”
“Here’s what you might notice change at home, and what stays the same.”

The goal is to get ahead of the inevitable parent questions before they show up at the front office.

The gap-analysis step

The single most important non-obvious step is gap analysis at the student level. Build (or download) a simple two-column reference:

Left column: every phonics pattern in the new (Wilson) sequence, in order.
Right column: every phonics pattern in the old (UFLI) sequence the student has mastered, mapped against the left column.

The students you care about are the ones whose mastered patterns map to a high lesson number in the new sequence but a low lesson number in the old — or vice versa. A first-grader who finished UFLI Lesson 60 is in different territory than a first-grader who finished UFLI Lesson 30, even if they’re both in the same classroom. Wilson’s grade-level starting point will under-challenge one and over-challenge the other.

This work happens once, takes a few hours per grade level if your coach builds the reference template, and prevents the most common post-switch failure: students treading water for a quarter because the new lesson they’re on doesn’t match what they’re ready for.

Where Storytime fits

This is the section where we name what our platform actually does for the migration, because it’s directly relevant.

Storytime cross-tags every book in its decodable library against the lesson order of both UFLI Foundations and Wilson Fundations (and five other curricula). On the day a school switches its core program, the practice layer doesn’t have to switch — the same books are available, mapped to the new sequence. On-demand decodable generation respects the new curriculum’s phonics caps automatically. The library doesn’t get smaller; the tagging that surfaces books to students gets re-pointed.

For the journey-building side of the platform, the rebuild is explicit. When a school changes its primary curriculum, teachers rebuild their assigned reading journeys against the new scope and sequence. The student-level phonics inventory data (what patterns have been demonstrated through ORF passages, quizzes, and book reads) carries forward and informs where in the new sequence each student starts. Screener data carries forward.

That said, no platform changes the underlying instructional work. The PD is still real. The parent communication is still real. The gap analysis is still real. A digital practice layer reduces the decodable-book mismatch problem and lets you avoid rebuilding your assessment history, but it doesn’t replace the work of running a curriculum well.

A note on hybridization

A few districts caught mid-year with crates of UFLI workbooks they can’t return choose to run a hybrid transition term — UFLI as the structured warm-up and review block, Wilson Fundations as the formal core. This is operationally messy and shouldn’t be a long-term plan, but for one quarter it can be a pragmatic way to use unspent materials while teachers complete certification. The risk is fidelity drift: two competing scope-and-sequences in the same classroom dilute both. If you go this route, set an end date in writing and stick to it.

Bottom line

A forced mid-year curriculum switch is one of the harder asks in elementary literacy. Both UFLI Foundations and Wilson Fundations produce strong outcomes when implemented with fidelity, but the migration between them isn’t a paperwork exercise — the scope-and-sequence differences, the certified PD requirement on the Wilson side, the decodable-text mismatch, and the parent-communication overhead are all real costs that need explicit planning.

The good news: heart words, screening data, ORF records, and decoding habits all carry over. The PD is finite. The gap analysis is a one-time exercise. The new program will work if you give it the runway it deserves and the implementation support its publisher recommends.

The switch is rarely the teachers’ choice. Landing it well is.
