Why Adding More Rarely Improves Instruction
By Olivia Odileke
A school adopts a new literacy program. Comprehensive. Research-based. Teachers get trained. But six months in, implementation is uneven, so the principal adds a coaching cycle. Then a fidelity checklist. Then follow-up training.
A year later, data improved slightly. But teachers are exhausted. Morale is lower.
The principal thought: We need more support. More training. More clarity.
But here's what might actually be true: the problem wasn't that there wasn't enough. The problem was that there was too much.
This is counterintuitive, but it's worth naming: adding more rarely improves instruction. It usually makes it worse.
The Hidden Cost of Overload
When a teacher is responsible for a new literacy framework, differentiating for five learning levels, using a new classroom management system, a new data dashboard, monthly PD, and accreditation prep—she's not going above and beyond.
She's drowning.
And when you're drowning, you don't learn deeply. You survive. You do the minimum on everything. You get a little bit of the literacy program. A little bit of the management system. A little bit of everything.
The instruction doesn't improve. It fragments.
What gets lost first is the thing that's hardest to measure: thinking. The space to actually integrate something into your practice instead of just adding it on top.
Teachers become checklist completers. Leaders become change managers trying to squeeze one more thing into a cup that's already overflowing.
What Capacity Actually Looks Like
Human capacity is real. Cognitive load is real. When you exceed them, something breaks.
Research on change management shows that initiatives take 3-5 years to actually shift practice. They require coherence the sense that everything is connected around a shared purpose. And they require capacity—time, attention, and mental energy to take root.
But most schools add something new every year, sometimes every semester. They layer initiatives on top of each other without connecting them or releasing older ones.
Then they're surprised when nothing quite works.
The problem isn't the initiatives. The problem is the architecture of how they're introduced and supported.
The Cost of Incoherence
There's something else that happens when a school keeps adding: the work stops making sense.
A new literacy program emphasizes close reading and text-dependent questions. At the same time, the school implements project-based learning that emphasizes student choice and inquiry. A teacher tries to honor both and does both poorly because they live in her mind as separate things.
Meanwhile, she's using a data dashboard that measures something slightly different than the learning framework adopted last year.
Everything feels disconnected. When teachers can't see how pieces fit together, they treat each piece as an isolated requirement. Close reading becomes a box to check. PBL becomes a unit she does once a month.
The initiative loses power because the initiative was never actually about coherence. It was about accumulation.
The Principle of Subtraction
Here's a different approach: what if improvement came from subtraction instead of addition?
This requires naming something hard. It requires asking: What are we doing now that we could stop doing?
Not because it's bad. But because we're doing too many things to do any of them well.
What if a school said: We're going to stop doing the monthly data disaggregation meeting so that we have time for teachers to collaborate deeply on the literacy program we've chosen.
What if a school said: We're releasing the classroom management protocol we adopted two years ago. That time can go toward something that matters more right now.
What if a school said: This initiative hasn't taken root. We're going to pause it and focus on getting the foundational work solid.
Subtraction is hard because it feels like you're going backward. But actually, subtraction creates the conditions for real improvement. Because improvement requires depth, and depth requires focus, and focus requires removing everything that's not essential.
Designing for Focus
Let's return to the design question: what inputs are you creating?
When you add a new initiative without subtracting something else, the input you're creating is: This matters more than your current work. And your time is unlimited.
The condition that creates is: I can't possibly do everything, so I'll do the minimum on everything.
When you add something while naming what you're releasing, the input you're creating is different: We've thought about your capacity. Deep work on a few things matters more than surface work on many things.
The condition that creates is: I can actually think about this work. I can get good at it.
One input creates fragmentation. The other creates focus and learning.
The Questions to Ask
Before you add the next initiative:
What am I taking away to make room for this?
If the answer is nothing, you're not ready.
How will this connect to work that's already happening?
If you can't draw the connection clearly, the coherence isn't there yet.
How much time does this actually require—and where will it come from?
Be honest about capacity. Teachers know the truth even if you don't say it.
A Closing Reflection
Your job as a leader isn't to add more. It's to create the conditions where fewer things, done well, create better outcomes.
This requires more discipline. It requires more honesty about capacity. It requires more faith that depth will create outcomes faster than surface-level accumulation ever will.
But it's actually true. And it's actually available to you.
What would become possible if you subtracted instead of added?
For Further Reflection
Michael Fullan, Change Forces: Probing the Depths of Educational Reform (1999) Fullan's research on educational change explores why most initiatives fail to create lasting impact and how pacing, coherence, and capacity building are essential to real improvement.
Jim Collins, Good to Great (2001) Collins' research on organizational excellence emphasizes the power of focus and the discipline of subtraction—doing fewer things exceptionally well rather than attempting too much.
Paul Hersey & Ken Blanchard, Situational Leadership (1969) Hersey and Blanchard's framework shows how overloading people with new responsibilities undermines learning and performance—capacity and pacing matter.
