My Students Read All Over the Map. How Do I Make Science Accessible Without Watering It Down?

A teacher put this to me recently, and the tension in the question is real. Her class spans a wide range of reading levels, some students well above grade level, some well below, several still building academic English, and she feels caught between two bad options. She can hand out grade-level science text and lose the students who cannot yet decode it, or she can simplify the material and worry she is lowering the bar for everyone.

It is a fair worry. But the choice she is describing is a false one, and it comes from a particular assumption about what "reading level" tells us and what accessibility requires.

Here is the assumption worth questioning: that reading comprehension is a general skill students carry from class to class, so a student who "reads below grade level" will struggle with any text you give them. In science, that is not how comprehension works. Comprehension in a discipline depends far more on what a student knows about the ideas in the text than on a general reading score. A student who has spent a week figuring out why one population of fish became hundreds of species can read a challenging passage about speciation, because the text now maps onto something they have thought hard about. The same passage handed to a student cold is genuinely inaccessible, not because of their reading level, but because they have no conceptual foothold.

That reframing changes what accessibility means. The goal is not to sort students by reading level and hand them different versions of the text. It is to build the knowledge that makes the text readable, and to build supports into the task that every student can use. Below are six keys for doing exactly that.

Five Keys for Access Without Dilution

1. Build knowledge first, then read. The most powerful thing you can do for a struggling reader is to make sure they know something about the topic before they read about it. When students have investigated a phenomenon, analyzed some data, or argued about a possible explanation, a text stops being an entry point into unfamiliar territory and becomes a resource they are ready to use. Reading placed after sensemaking is dramatically more accessible than the same reading placed before it, for every student in the room, but especially for the ones who read below grade level.

2. Give the reading a job. Students read far more successfully when they are reading to accomplish something rather than to "cover" a text. Use reading to confirm and name a pattern students already discovered, or to fill an identified gap in an explanation they are trying to build. "Read this to find out whether it supports our group's claim" produces closer, more motivated reading than "read pages 112 to 115," because now the student has a reason to make sense of the words on the page.

3. Treat talk, not just text, as a source of ideas. Reading is one way into disciplinary ideas, but it is not the only one, and leaning on it exclusively disadvantages your developing readers. Structured student talk, short videos, diagrams, data displays, and hands-on investigation all put ideas on the table. A multilingual learner who is still building English can reason powerfully about a phenomenon they have watched and discussed, and that reasoning gives them the conceptual grounding that makes the eventual reading work.

4. Make peer talk carry the load that a leveled worksheet would. When a classmate asks, "How do you know that?" it lands harder than the same question from a teacher, and it sends a student back to the evidence. A gallery walk or a structured share-out multiplies these moments and makes them available to everyone in the room at once. The talk itself is the support, and unlike a leveled reading, it does not require you to decide in advance who gets the harder version and who gets the easier one.

5. Build access into the task instead of distributing it by label. Notice what this approach does not do. It does not sort students by reading level, language status, or prior proficiency and hand them different versions of the work. It builds the supports a differentiated classroom would distribute unevenly: the accessible entry point, the knowledge-building before reading, the sentence starters, and the structured talk, all built directly into a single experience that every student shares. The access opportunities become features of the task, available to all, rather than accommodations triggered by a label. Every student works on the same rigorous science; what differs is not the task but the resources each student draws on to engage with it.

Putting It All Together

The reason "accessible" and "rigorous" feel like opposites is that we usually pursue access by changing the text, simplifying it, shortening it, handing different versions to different students. That approach does trade rigor for access, and it does it by deciding ahead of time what each student is capable of.

But most of what makes a science text hard for a struggling reader is not the prose. It is the missing knowledge the prose assumes. Build that knowledge through investigation and talk before students read, give the reading a real purpose, and put the supports into the task rather than into leveled handouts, and the tradeoff mostly dissolves. You end up with a room where every student is doing the same demanding science, supported well enough to actually do it.

How ADI Makes This Easier

Sequencing a unit so that knowledge-building comes before reading, giving each text a genuine job in the larger investigation, and designing tasks with the supports built in is demanding design work to do on your own every week.

That is exactly the work Argument-Driven Inquiry (ADI) materials do for you. ADI investigations open with an accessible phenomenon that asks for no prerequisite reading level or vocabulary, position reading as a tool students use once they have ideas to bring to it, and build the entry point, the structured talk, and the writing supports into a single shared experience rather than a set of leveled variants. The design work behind these keys is already done, and the structure of the lesson supports the rest.
