Differentiation tools help one lesson reach students who read at different levels or in different languages. The most common job is rewriting a text: take an article or a passage and produce versions at several grade levels, with vocabulary support and questions. Other tools read text aloud, simplify hard words, or add picture support for students who need it.
AI rewriting is fast, and it is also where meaning can slip. A simpler version can drop a qualifier, change a cause into a coincidence, or turn an uncertain claim into a fact. Read each version against the original before students see it, especially for science, history and anything sensitive.
Leveled libraries like Newsela and CommonLit take a different approach: people write and check the leveled versions in advance. That means fewer surprises, at the cost of choosing from what the library offers rather than your own source. Many teachers use both, a library for core texts and an AI tool for the extra article that came up in class.
Text-to-speech readers support students with reading difficulties and students who simply learn better by listening. Some schools provide these tools as part of formal accommodations. If a student has a plan that names a specific tool, follow it and talk with your special education team before you swap in something else.

For multilingual learners, a translated version can help with access, but it can also replace the English practice the student needs. Decide with your English language team when a translation helps and when a simpler English version is the better support.
A good routine is to keep one original text and a small set of leveled versions together in your course materials, labeled clearly so you can find them next year. Students notice when they always get the easier version, so some teachers let students choose, or give everyone the same questions with different texts. Discussion still works when students read different versions, since they share the same ideas and can compare what they found. Keep an eye on what students pick and nudge them toward a harder text when they are ready.
Reading-level scores themselves are rough guides. Two passages with the same score can differ a lot in how hard they feel, depending on background knowledge and how the ideas are organized. Use the level as a starting point and trust what you see when students read.
It can be close for routine texts. Libraries are checked by editors in advance, so they are safer for core reading. Always read AI versions before you hand them out.
Several can. Decide with your language team when a translation helps and when a simpler English text gives better practice.
They can be part of one. If a student has a formal plan, follow what it says and check with your special education team before changing tools.
Compare it with the original for facts, cause and effect, numbers and tone. Simpler sentences sometimes change what a text actually claims.
