No date fits this
Nothing in the calendar matches these filters. Clear them to see everything, or tell us which course and which period you are after. As soon as we schedule a date, you hear about it first.
A complete foundation in two days
Take the introduction and Advanced back to back and you build a complete foundation in two days. In the introduction you learn to put Copilot to work in your daily job, in Advanced you go further with your own use cases, agents and setting up your work processes more intelligently. There are a few weeks between the two days, so you can let the first one settle into your own work first.
The combined rate is per participant and cannot be combined with the early-bird rate or the duo discount. You book both days in one go; we invoice as soon as both dates are confirmed.
From booking to training day
Four steps, no surprises. You know where you stand well before the start.
Choose a date
Filter by theme, month or format and pick the date that suits you. Every card links to the full programme of that course.
Book your place
The form takes a minute and you pay nothing yet. Within one working day you receive a confirmation by email, with the calendar invitation included and the date up to which you can cancel free of charge.
We confirm the date
A date goes ahead from six participants. No later than fifteen days before the start you hear by email whether we made it; only then do we send the invoice.
You prepare briefly
About a week ahead we send a short questionnaire: where do you get stuck, and which files do you work with? We use it to match the examples to your own practice.
What you want to know beforehand
The arrangements that apply to every date, gathered in one place. If your question is not here, just give us a call.
- Location
- On-site training days take place in The Hague, somewhere easy to reach. Not a strip-lit meeting room, but a space you will happily spend a day in. You receive the address and travel directions by email as soon as the date is confirmed.
- Group size
- Six participants at least and twelve at most. At twelve there is still time to help everyone personally; below six the conversation in the group never really starts. If we do not reach the minimum, we move the date.
- Early bird
- Up to four weeks before the start you pay the early-bird rate. Every date in the calendar shows how long that lasts and what you pay afterwards.
- Duo discount
- Coming with two or more from the same organisation takes 10 per cent off. It does not stack with the early-bird rate: we always charge whichever is cheapest.
- Booking closes
- The button on the card stays available until two days before the training day. After that online booking closes and the card says so. Do call to ask whether a place is still free; close to the day it often works out.
- Confirmation
- No later than fifteen calendar days before the start you hear by email whether the date goes ahead. If a date does not go ahead, we move it and your booking lapses at no cost.
- Cancellation
- Free of charge up to twenty-one calendar days before the start, no reason required. After that the terms in our general terms and conditions apply.
- Substitutes
- Cannot make it? Send a colleague in your place. That works up to the morning of the course itself, in consultation and at no extra cost.
- Included on site
- The day is fully catered: a proper lunch, drinks throughout the day, the workbook and a personal certificate of attendance. There is nothing else to pay.
- Included online
- Digital workbook, recordings of the demonstrations to review later, and a personal certificate of attendance.
- Prices
- Per participant and excluding 21% Dutch VAT. Every amount also shows the price including VAT, so you do not have to do the sums.
- Payment
- You pay nothing when you book. You receive the invoice as soon as the date is confirmed, roughly two weeks before the start, and settle it before the training day. If you book later than that, the invoice follows right after your booking.
Coming with six colleagues or more?
From roughly six participants within one organisation, an in-company course is usually better value than individual bookings. We then build the programme around an intake conversation and the way your organisation actually works, and use your own files during the day. Date and location in consultation: online, at your office, or at a rather good training venue in The Hague. Not a strip-lit meeting room, but somewhere people tend to stay on for a while at the end of the day.
Also in-company, without a fixed date
These subjects are not on the calendar, but we do teach them in-company. Date, length and make-up of the group are then yours to decide.
Open enrolment in short
A date goes ahead from six participants. No later than fifteen calendar days before the start we let you know whether the date is confirmed. If we do not reach the minimum, we move the date. If the new date does not suit you, your booking lapses at no cost.
Twelve participants at most. That leaves room for questions about your own work and gives everyone personal attention from the trainer.
The content is the same. Online you work from your own desk via Microsoft Teams, in two half-day blocks. On site you train for one uninterrupted day in The Hague, with lunch, drinks and the workbook included.
On-site training days take place in The Hague, somewhere easy to reach. We do not book a standard meeting room; we look for a venue where a day of training does not feel like a day of meetings. You receive the address and travel directions by email as soon as the date is confirmed, well before the training day. The day itself is fully catered: a proper lunch, drinks throughout the day, the workbook and a personal certificate of attendance.
You can cancel free of charge up to twenty-one calendar days before the start. After that the cancellation terms in our general terms and conditions apply. Sending a colleague in your place is always possible, in consultation.
You receive a confirmation by email within one working day, including the calendar invitation. About a week before the start we send a short questionnaire so we can match the examples to your own work.
There are two discounts. The early-bird rate applies up to four weeks before the start and is shown with every date in the calendar. The duo discount of 10 per cent applies from two participants from the same organisation. The two cannot be combined with each other; we always charge whichever is cheapest.
The amounts shown exclude 21% Dutch VAT. We also show the amount including VAT with every price. You receive the invoice as soon as the date is confirmed, roughly two weeks before the start, and pay before the training day.
Let us know through the contact form. As soon as we schedule a date, you will be the first to hear. From roughly six participants within one organisation, an in-company course is often better value than individual bookings.
We are glad to think along with you
