Most Arabic curricula are built for children and numbered by school year. Silsilat Al-Lisan (سلسلة اللسان) is built for non-native speakers and named by stage — and that one difference solves a problem almost every mixed-age class and adult learner runs into.

How the series is built

Four stages, each in two volumes, so eight books in the core ladder:

Alongside the ladder sit two support titles: the Tadribat book (تدريبات — the series' exercise companion) and a Teacher Guide.

Why stage names matter more than they sound

Consider a weekend class holding a nine-year-old, a thirteen-year-old and a fifteen-year-old who are all genuine beginners. In a numbered series, someone has to tell the fifteen-year-old they are in "Level 1" — a book visibly designed for a child, with a number that reads as a verdict.

In this series, all three are in Al-Kitab Al-Mubtadi', the beginner book. Nobody has been demoted. The name describes the Arabic, not the student.

That matters practically in three situations:

• Mixed-age classes, which is most weekend schools once you get past the youngest years.
• Adult and teenage learners, who abandon a course faster than children when it feels beneath them.
• Converts and returning learners, who often speak some Arabic but cannot read it, and are poorly served by any age-graded ladder.

Placement: the series tells you its own entry criteria

This is the most useful feature of Silsilat Al-Lisan and the reason self-placement actually works with it. Each stage states who it is for in terms of what the learner can do, not how old they are or which book they own.

Preparatory (Tamhidi) — described by the publisher as the cornerstone for all learners of Arabic, running across two volumes and covering the topics needed in everyday life, beginning with how to read. This is the true zero point: start here if the learner cannot read Arabic script.

Beginner (Mubtadee) — for those who have finished Tamhidi, or those who already have vocabulary sufficient for everyday life and basic communication. That second clause is the important one. A learner who grew up hearing Arabic at home, has words but no structure, can start here without pretending to be an absolute beginner.

Intermediate — the third phase, for those who have completed Tamhidi and Mubtadee, or those able to compose sentences of all types in Arabic. That is a concrete, testable standard: can the learner build a nominal sentence, a verbal sentence, a question, a negation? If yes, they belong here regardless of which books they have owned.

Advanced — the fourth and final stage, for those who have completed the first three.

Take ten minutes and test against those criteria rather than guessing. Ask the learner to read a short passage aloud, then to make four different kinds of sentence about it. Their answers place them more accurately than any form they fill in.

Who this series suits

It fits well if:

• Your learners are not native Arabic speakers — that is the audience the series was written for, rather than a children's curriculum adapted afterwards.
• You teach mixed ages by ability, or one-to-one.
• Your students are teenagers or adults who would find a primary-school book patronising.
• You want a ladder that ends somewhere definite. Four stages, then done.

It fits less well if:

• Your school organises strictly by year group and wants a book per grade with the grade printed on it.
• You are teaching young children — a series with games, songs and heavy illustration will hold a six-year-old better.
• You need a large classroom ecosystem of posters, flashcards and activity packs. This series is a focused ladder with an exercise book and a teacher guide, not a resource library.

Getting the most from it

Buy the Tadribat book with the textbook, not after. Adults consistently under-practise, because reading a page feels like progress in a way that doing twenty drills does not. The exercise companion is what converts recognition into recall, and a learner who buys it three months late has usually stalled by then.

Buy the Teacher Guide even if you are teaching one child at your kitchen table. Guides get skipped by parents to save money, and the result is improvisation that burns out by November. It is the cheapest hour of preparation available.

Do not rush Tamhidi. The preparatory stage is where reading is built, and every later stage assumes it silently. A learner pushed forward before they read fluently will appear to be struggling with grammar at the Intermediate stage when the real problem is decoding, three stages back.

Expect the second volume of each stage to take longer than the first. Volume 1 introduces, volume 2 consolidates and extends — and consolidation is slower, which surprises learners who timed their year on how quickly volume 1 went.

Planning the timeline

Eight books sounds like eight terms. It rarely works out that way, and planning as if it will is how schools end up abandoning a series two stages in.

The honest shape: the preparatory stage takes the longest relative to how little it appears to cover, because it is building reading itself, and reading is a motor skill that resists being rushed. Learners often spend as long on Tamhidi 1 as on an entire later book, then accelerate sharply once decoding becomes automatic.

Two consequences for anyone budgeting a year:

• Do not promise parents a stage per term. Promise a stage per year for the preparatory phase and revisit after that.
• Do not judge the series by the first eight weeks. The preparatory stage is the least rewarding to teach and the most decisive for everything after it.

One-to-one versus a class

This series works unusually well one-to-one, which is worth knowing because most curricula do not.

Because placement is by capability rather than year group, a tutor can start an adult exactly where they are, skip nothing, and move at the learner's pace without the book fighting them. There is no cohort to keep together and no age signalling to manage.

In a class, the same feature becomes a scheduling advantage: you can run two stages in one room. Beginners work the Tadribat exercises independently while the teacher takes the intermediate group through new material, then swap. That is far harder with a series where the books assume lockstep progress.

What it does not do is entertain a restless group on its own. There are no games, songs or activity packs built in. If your Sunday class needs energy in the room, the teacher supplies it — the books will not.

Where it sits among the alternatives

Silsilat Al-Lisan is the right answer to a specific question: how do I teach Arabic to non-native speakers of mixed ages without insulting anyone? If your question is different — a graded programme for a school organised by year, or a heavily supported classroom series — other options fit better.

Our guide to Arabic curricula for weekend schools compares the main choices against the teaching hours you actually have, which decides this more often than curriculum quality does. Adults studying alone should also look at our Mastering Arabic guide, which covers the main self-study alternative in English.

If you are also choosing an Islamic studies series — a separate strand with separate books — start with the complete level guide for that side.
