Introducing CEFR‑T (CEFR-Teach): A Vocabulary Ladder Built for How We Actually Teach.

For years, almost everyone teaching English has leaned on the same six letters: A1, A2, B1, B2, C1, C2; the levels of the *Common European Framework of Reference*, or CEFR. They’re useful. They’re everywhere. And, quietly, they’ve never quite fit the student in front of us.

Today we’re rolling out our own refinement of that ladder. We call it CEFR‑T for “CEFR, Teacher’s edition”. This post explains where it comes from, why we built it, and what it changes for your child’s learning here at Nelson Academy.

Most published “CEFR” word lists you’ll meet are really Oxford’s interpretation (ex. The Oxford 3000 and Oxford 5000 word lists). These take a large corpus of real English (newspapers, books, conversation) and tag each headword with the CEFR level at which a learner is likely to meet it. It’s careful, corpus‑driven work. But it’s calibrated around how English appears to a broadly *Western* audience. “Native frequency” is doing a lot of the sorting.

CEFR‑J comes at the same problem from the other side of the world. Developed in Japan (by Tono and colleagues) for East‑Asian learners of English, it noticed something every ESL teacher in Japan already knows in their bones: the standard A‑and‑B bands are far too wide for the years our students actually spend inside them. There are over 1400 words at the A1 level — a learner can sit “at A1” for a very long time. So CEFR‑J breaks the lower levels into finer steps and re‑orders the vocabulary around what an Asian EFL classroom really introduces first.

That re‑calibration is exactly why we adopted CEFR‑J over Oxford as our level authority in previous years. For our students, it simply describes reality better.

Two reasons, one practical, one philosophical.

1. Even CEFR‑J’s A1 is too large. We simply do not need more than 400 or 500 words in a particular band. A label is only useful if it tells you what to teach next, and a band of 1,500+ words tells you nothing.

2. We wanted the levels to mean something a parent can see on a shelf. Walk into any bookshop in Taiwan and you’ll find the graded English magazines — the ones organized by difficulty with one star, two stars, three stars (* / * / ***), running roughly 500 to 2,000 headwords. Beginner titles. Intermediate titles. Advanced titles. That tiered, star‑rated world is the one our student already lives in. What if our vocabulary levels mapped straight onto it?

That’s CEFR‑T.

CEFR-T Roadmap

Thirteen bands, plus “unrated,” with roughly 500 words each; about 6,500 headwords end to end:

| Tier          | Bands        | Maps to...                                        |
|---------------|--------------|---------------------------------------------------|
| Prerequisite  | A0           | The first 250 to 500 words a student will learn.  |
| Beginner      | A1 · A2 · A3 | Beginner level *, ** and *** words. Gradeschool.  |
| Intermediate  | B1 · B2 · B3 | Intermediate level *, ** and ***. Highschool.     |
| Advanced      | C1 · C2 · C3 | Advanced/University level.                        |
| End‑game      | D1 · D2 · D3 | Very difficult or obscure words                   |

The trick is the third sub‑level. Where standard CEFR gives you A1 and A2, CEFR‑T gives you A1, A2 and A3; three honest steps that line up with three stars. Suddenly “what comes next” is a small, teachable hop instead of a plateau that lasts years. A0 anchors the bottom with the genuinely-first words, and the D tail keeps our games from ever running out of hard material for a strong student.

Textbooks

Besides periodic material, how does this line up with textbooks? Very tentatively, we can seed almost all of the books in the A-level. It is highly likely that we would do something like:

• Wonderskills has Starter (Yellow), Basic (Red) and Intermediate (Green) with three books per level. We can use A0 for starter, A1 for basic and A2 for intermediate.
• EasyLink has L1, L2, L3 to L6 and maybe more. The early books are A0, then A1, as the crow flies.
• Reading Sketch Starter is probably A0, with Reading Sketch likely at A1-A2.

By A2 we can already allow 1000-1500 words; if these books are teaching words that are out of these bands, they are bad textbooks. But moreso than this, the headwords themselves are often not really the main point of the lesson. It’s the reading itself — what does it reinforce from lesson to lesson, that is most important. Headwords are important but great consideration must be given to words that are simply assumed. This will be an ongoing challenge to rate words effectively but, if a student is required to know the word at the Starter level it is clearly an A0 word. Basic, A1, and intermediate A2.

After this level of textbook instruction, I feel that moving to more advanced material (especially periodic content) is the next step. Or, more advanced static work such as Magic Treehouse.

Readers: The Parallel Concern

In addition to the above, the system must also carefully match the readers we use, which are primarily the Oxford Reading Tree or Oxford Story Tree series. We find red books to be A0, blue to be A0/A1, Green to be A1/A2, with Orange fleshing out the remainder of A2. Higher levels such as Pink really belong in A3 or B1. If a student is reading pink level (The Litter Queen, Bully, Kidnappers, etc.) they are beyond * and possibly ** level in magazines like “Let’s Talk in English.”. The A2/A3 rating supports this theory.

Primary Use Case: Textbook Selection

All in all there is quite a lot of room in the A series. Pegging a student as A0, A1, A2 or A3 will enable the proper choice of textbook early on. If a student is testing above the A3 level, they may be ready for readers above the Magic Treehouse level, with true B-level students able to start studying American newspapers, and later, classic gradeschool novels like Freckle Juice — early classics like if you give a mouse a cookie — and so on. If a teacher’s job (considering MCI/N+1) is presenting the right material to the students at the right time, CEFR-T suddenly becomes one of the most important metrics a teacher can have. It can help plug clear holes in a student’s knowledge and provide the fertile ground they need to truly enable MCI (massive comprehensible input) and FSR (free sustained reading) to work their magic.

We are very excited to use this new system to help students learn English!
