How it works

Three steps to your first class.
Get matched
With the right class, level, and schedule for you. The studio picks your teachers; you don't have to choose from a marketplace.
Start learning
Real progress from your very first class. Live classes in small groups. Most are taught in rotation by the same two teachers all year; some by one.
Our model
Owned by the teachers who teach you.
Signal is a cooperative. The teachers who run your class also run the studio, together with the administrator who keeps it working. They set the curriculum, plan every class, and stay because the work is theirs.
That changes the things students feel without naming them: teachers who don't churn, classes that aren't rushed, a school that isn't built to be sold.
How the cooperative works
6
members own and run the studio together: five teachers and one administrator. No investors, no shareholders.
Programs
Built around what you actually need to do in English.
For teens and adults
General English, online, by the hour you actually have.
Small live groups. Weekday evenings and Saturday mornings, in your timezone. Conversation-led from A1, with real teachers you'll keep all year.
Read, write, listen, speak. Not in that order, and not always in the same week. The textbook follows the class, not the other way around.
See the program Exam prepCambridge B2 to C2.
Targeted prep for B2 First, C1 Advanced, and C2 Proficiency. A mock exam every semester and free weekly exam practice included.
See exam tracks ConversationFor students who already speak, and want to actually use it.
Once or twice a week with the same teachers, in small live groups. Topic-driven, low on grammar drills, high on talking. Built for B2 and up.

The method
Three things we believe about teaching English.
Not a proprietary method. Just what we've found, after thousands of classes between us, actually works.
Small live groups, real conversation.
Group sizes stay small so you speak in every class, from the first one. The textbook is scaffolding, not the lesson.
CEFR as a map, not a cage.
You'll know your level (A1 to C2) and what comes next. But the path is built around what you need to do in English, in the order you need to do it.
Teachers who stay.
Because the teachers are co-owners, they don't rotate out for better-paying gigs. Your teacher next year is the one you have now.
