English Language Training
Online English Course: One-on-One Language Training for Professionals & Private Clients
Do you find that your English vocabulary falls short during an important business meeting? Or do you feel that familiar barrier to speaking as soon as you have to present, negotiate or simply make small talk while travelling? Traditional classroom group lessons are often too slow, don't match your sector and take up too much time in a busy diary.
At Instituut Jeroen Bosch, we take a different approach to online language training.. With our 100% online one-to-one English training, you work one-on-one with a highly qualified, certified trainer on your personal goals. No distraction from a group, no travel time, but maximum focus on your success.

- 100% online, 1-on-1
- Certified trainers in the Netherlands
- Cedeo-certified
- Smart app + extensive self-study material
Why choose our one-on-one English course?
We combine the best of both worlds. As a label under The Square Mile (25 years of experience), we build on the rich history of Instituut Jeroen Bosch (a trusted name since 1968). This means you rely on more than 75 years of teaching expertise, translated into a flexible learning method for today.
Focused language training. Real results.: Take your lessons wherever and whenever it suits you, fully digital and fitting neatly into your schedule for maximum impact.
Cedeo-certified: Our exceptionally high customer satisfaction and professional approach are officially recognised.
Certified Trainers in the Netherlands: Learn from highly qualified trainers based in the Netherlands who truly understand where you’re starting from. Being based in the Netherlands makes scheduling effortless, while your trainer guides you through typical false friends, refined pronunciation, and specific vocabulary, with deep insight into British or American culture and international business contexts.
The 50/50 formula: maximum results at a friendly price
50% live online coaching: intensive one-on-one sessions with your personal English trainer.
50% focused self-study: practical, interactive exercises through our smart app and the material.
We track your progress precisely according to the Common European Framework of Reference for Languages (CEFR), from level A1 through to C2. Throughout, we stay realistic: while you often make big leaps quickly at lower levels, the finer points on the way to fluent English (towards C1/C2) take time and consistent effort. Your motivation during self-study is the key to success here. That is why we make no hard guarantees about a final level, but we do offer you the very best guidance.
