Third-Grade Reading Fell 19 Points. Now What?
At Lincoln Elementary, third-grade reading proficiency on the winter benchmark fell from 68% to 49% in one year, while fourth and fifth grades held steady. The decline is concentrated in the four classrooms piloting a new structured-literacy curriculum; two of those teachers are in their first three years. Walkthrough notes show 90-minute blocks where roughly 55 minutes is whole-group instruction and worksheets, with about 12 minutes of small-group work. The principal's calendar is consumed by 42 required evaluations due this semester. Two veteran teachers say the curriculum 'doesn't work' and have quietly reverted to the old basal reader. The district expects a mid-year data report in five weeks, and the superintendent has asked for a 'root cause, not an excuse.'
1. Diagnose the most likely causes of the decline and explain what evidence you would gather before acting. Distinguish between what the data do and do not tell you.

What the data do not say
The benchmark does not say the curriculum failed. It does not isolate teacher effect, does not control for cohort, and does not rule out a change in the assessment form or cut score. Before I attribute cause I need three checks that take a day, not a semester.
Checks I would run first
- Form and standard-setting: did the winter form or the proficiency cut change? A 19-point drop with grades 4–5 flat is consistent with a grade-3-specific artifact.
- Cohort history: where was this cohort in grade 2? If they entered third grade below the prior cohort, part of the drop precedes the curriculum.
- Implementation fidelity: the walkthrough pattern-55 minutes whole-group, 12 minutes small-group-is the signature of a structured-literacy block being taught around rather than with. That alone could produce this result regardless of program quality.
Most probable causes, ranked
Implementation infidelity across a partial rollout, compounded by two of four teachers being in years 1–3 without coaching, and by two veterans teaching a different curriculum entirely so that grade-level data now mixes two programs. Item-level analysis will tell me whether the losses cluster in the specific strands the new curriculum sequences differently.
What I would say to the superintendent
Not 'the curriculum doesn't work' and not 'the kids came in behind.' Something falsifiable: the block is not being delivered as designed, here is the fidelity evidence, here is the correction plan, here is what will tell us in six weeks whether I am right.
2. Two veteran teachers have reverted to the old basal. Describe your response-what you would say, and what you would do if they continue.

Do not open with compliance
These are experienced teachers with a defensible professional view. I open with data and a genuine question: 'Show me what you're seeing. Which strands are collapsing, and what does your basal do differently there?' If they can demonstrate it, that is program information I need, not insubordination.
Then make the non-negotiable explicit
- The district-adopted curriculum is the expectation; parallel instruction in two of four classrooms makes grade-level data uninterpretable and is unfair to the two new teachers who have to follow a program their colleagues openly disregard.
- I would offer a fair test: teach the adopted program with fidelity for six weeks, with me in the room weekly, and bring the evidence to the grade-level team. If it still underperforms against a comparable group, that is a legitimate basis for a program conversation-with the district, not in secret.
If it continues
I move to a written directive with a specific observation window, document the conversations, and use the supervision process I already have-not a surprise evaluation. I would also check whether I am asking them to do something I have not resourced: peer observation, materials, and coaching time.
The mistake I would avoid
Letting the two veterans be the only consequence while the two newest teachers absorb the implementation burden silently. That teaches the whole staff which way the wind blows.
3. Forty-two evaluations are due, you are five weeks from the district report, and the real problem is Tier 1 instruction. How would you restructure your time and your levers?

Trade scarce time against the highest-leverage lever
Evaluations are a legal obligation; Tier 1 instruction is the thing I was hired to improve. Both matter, but they draw on the same 42 hours. I would protect evaluation compliance and reallocate everything else.
Time plan
- Triage the 42. Confirm which require full formal observations and which can be satisfied by shorter, walkthrough-based cycles under the contract. Audit my calendar and cut or delegate anything not legally mine-facilities, purchasing, volunteer coordination.
- Two protected coaching hours daily, spent only in the four grade-3 rooms, with a single focus: converting whole-group minutes to small-group minutes. That is a schedule intervention, not a philosophy seminar.
- Use the grade-level team meeting, already on my calendar, as the vehicle for data review, so I am not creating a fourth thing for tired people to attend.
- Deploy a coach or lead teacher to the two early-career teachers; I cannot personally provide the frequency they need.
The five-week report
Report the diagnosis and the correction plan with baselines and leading indicators-minutes of small-group instruction per block, weekly fluency checks-rather than promising a proficiency rebound that cannot appear by May. A principal who promises a 19-point recovery in five weeks has guaranteed that no one believes the next report.
