So the truth is that Reading ADZ graded readers aren't the best choice for most Chinese kids.

You see, REZ works best for the following three types of families.

First, it's families planning for an international education path.

Reading ADZ aligns with the CCSS, which is the US curriculum, Common Core State Standards, which focuses on problem-solving, analytical thinking and critical thinking, skills that most textbooks here in China simply don't teach.

Or it's also for families on a dual track, meaning local PLUS international path.

These skills take years to develop, so REZ readers help build them early.

For example, even Level A reading comprehension quiz asks questions likeHow are the shiny buttons and the small buttons alike?

This comparison-based thinking is the foundation of critical analysis.

And finally, it's also for families focusing on listening and speaking first.

You see, strong listening and speaking skills are a must before using REZ readers, or any other graded readers for that matter.

These books are a powerful tool because they're based on science of reading, a method backed by decades of research from psychologists, neuroscientists and linguists.

It proves that listening is the key in language learning.

So why is it that REZ graded readers aren't the best option for Chinese students?

See, it's because many start REZ without enough listening or speaking practice.

And that is the reason why they get stuck at higher levels.
