The Kingdom of English is an ESL and EFL platform built specifically for teachers. It covers grammar, reading, listening, writing, and vocabulary practice across 60 topics per skill area at B1 to C1 levels as defined by the Common European Framework of Reference for Languages (CEFR). Teachers can create classes of up to 60 students, assign targeted homework across all skill areas, and track individual and class-level progress. AI evaluates open-ended student responses in reading, listening, and writing. Pricing is €9.90 per month for a teacher plan with no per-student charges.
Most digital tools marketed to ESL and EFL teachers were not built by ESL or EFL teachers. They were built by software companies who surveyed a few classrooms, hired some curriculum consultants, and shipped a product that looks polished in a demo but falls apart when you try to use it with sixty real students who have varying levels, different homework habits, and no patience for clunky interfaces.
The Kingdom of English took a different approach. It was designed from the beginning by a teacher with more than ten years of experience in the ESL classroom — someone who has lived the daily frustrations of managing large classes, chasing homework completion, and trying to find a way to give every student meaningful feedback without working a sixteen-hour day.
This article explains what an ESL and EFL platform for teachers actually needs to do, and how The Kingdom of English addresses each of those needs practically. Whether you teach English as a second language domestically or as a foreign language abroad, the core requirements are the same. Institutions like the British Council have long advocated for integrated, skills-based teaching supported by consistent practice and progress measurement.
Before talking about features, it is worth being honest about the problems. Teachers who have tried various digital tools usually share the same complaints:
These are not niche concerns. They are the central problems that determine whether a platform gets used consistently or ends up as yet another subscription that sits unused after the initial enthusiasm fades.
The Kingdom of English is designed to handle a teacher's full roster. The teacher account supports up to 60 students in a single class, which covers the reality of most private language school contexts where teachers may be managing multiple groups across a working week.
Student accounts are created directly from the teacher's dashboard. The teacher sets up usernames and temporary passwords, students log in, and they are immediately connected to their teacher's class. There is no lengthy onboarding process, no requirement for students to have email addresses of their own, and no app to download. The platform runs in any browser.
This simplicity at the setup stage is not accidental. Every step of friction in the onboarding process is a student who does not quite manage to get connected. The faster a teacher can get an entire class active on the platform, the more value they will see from it.
A meaningful ESL and EFL platform for teachers needs to cover the full range of language skills, not just the ones that are easiest to automate. The Kingdom of English includes dedicated practice and assignment capabilities for grammar, reading, listening, and writing.
Grammar covers 60 topics from the B1 to C1 range, with exercises that include multiple choice, gap-fill, and sentence transformation tasks. Teachers can assign specific grammar topics as homework and students' completion is tracked automatically. Targeted review on topics such as verb tenses is especially useful when a class needs focused reinforcement after a lesson.
Reading provides 60 texts at different difficulty levels, each with comprehension questions that students answer after reading. The AI evaluates open-ended responses, which means students are not limited to picking from a list of options - they have to actually demonstrate understanding in writing.
Listening gives students access to 60 audio exercises with comprehension tasks. This is one of the skills most neglected by digital platforms, partly because audio content is harder to produce and partly because evaluating comprehension responses automatically has traditionally been difficult. AI evaluation makes this practical at scale.
Writing takes the form of longer tasks where students receive detailed AI feedback on their submitted work. Teachers can see what students have written, what feedback they received, and whether they have acted on it.
The progress tracking dashboard is one of the features that teachers consistently find most valuable once they start using it. For each student, the teacher can see which topics have been practiced, how many exercises have been completed, what scores are being achieved, and where a student is consistently struggling.
At the class level, the dashboard gives an overview that helps teachers make decisions about what to prioritize in the next lesson. If the data shows that most of the class is struggling with a particular grammar topic despite completing the practice exercises, that is useful information. It suggests the issue is not lack of effort but something in the way the topic was initially presented — or perhaps a conceptual difficulty that needs to be addressed differently in class.
Homework completion tracking also changes the dynamic of accountability in the classroom. When students know that their teacher can see exactly what they have done — or not done — the conversation around homework shifts. It is no longer the teacher's word against the student's. The data is simply there.
Getting students to show up to class is one challenge. Getting them to practice consistently outside of class is another challenge entirely, and one that most platforms do not solve adequately.
The Kingdom of English uses a gamification system that has been designed to maintain long-term engagement, not just generate a spike of interest in the first week. The system includes:
Teachers often report that the leaderboard alone is enough to significantly increase the amount of practice students do outside of class. Students who would never voluntarily do extra grammar exercises will spend twenty minutes on the platform because they want to close the gap between themselves and the student ranked above them.
The Kingdom of English is priced for individual teachers, not institutions. The Teacher plan costs €9.90 per month, or €99 per year for those who prefer to pay annually — a saving of roughly two months compared to the monthly rate. There are no per-student fees, no additional charges for specific features, and no hidden costs.
For a teacher running three or four groups of students, this works out to a minimal cost per student per month. Compared to the cost of producing physical worksheets, printing reading texts, or purchasing supplementary course materials, the platform pays for itself quickly if it results in meaningful improvements in student practice volume and homework completion rates.
New teachers can try the platform free for 7 days before committing to a subscription. This gives enough time to set up a class, explore the content, assign some exercises, and see how students respond — all without any upfront financial commitment.
There is a meaningful difference between a platform designed by educators and one designed by a software team that has spoken to a few educators. The difference shows up in dozens of small decisions: how assignments are structured, what data appears in the progress dashboard, how the student interface is laid out, what the onboarding process looks like.
With more than ten years of classroom experience informing every design decision on The Kingdom of English, the platform reflects what actually matters in day-to-day teaching practice. The features that exist are the ones that solve real problems. The features that are absent are absent because they would add complexity without adding value.
