Please note that participants are enrolled in the order of payment. Some of our courses are sold out each year, so do not miss the opportunity to join us this summer and pay your fee as soon as possible.

Online payment by Credit Card or IDEAL

After you have been admitted we will send you an AcceptEmail. With this email you will be able to pay your fee. You can either pay by Creditcard or IDEAL. For more general information about AcceptEmail please read the section below.

What is AcceptEmail?
AcceptEmail is a simple way of paying bills by email. You always receive an AcceptEmail directly from the beneficiary, so it is clear who sent the email and to whom you’re paying which amount. You decide when you pay, and the payment status color shows if you’ve paid or not. It’s easy and simple.

How secure is AcceptEmail?
Very. The only thing another person can do with your AcceptEmail is pay your bill. Your AcceptEmail does not contain payment details – and you will not be asked to provide any confidential information. During the payment process, you can always clearly see what amount you’re paying to whom. The payment will always run through a secure online environment. Just like you’re used to. For added security, AcceptEmails are signed digitally, and the content of the email remains encrypted until it reaches your inbox. This means the email you receive cannot be tampered with.

How does it work?
To pay, you simply click the payment button in the AcceptEmail. Upon clicking you land on the secured transaction page and choose your preferred payment method. All necessary information is already filled out for your convenience. All you need to do is confirm. Paying AcceptEmails can be done simply and safely via IDEAL or credit card.

I've received an AcceptEmail, but I can’t view it. What should I do?
If you can’t see any images, please check the security settings on your email program. You may need to change these settings to allow images to be shown automatically. Google has designated AcceptEmail as Trusted Sender. This means that most email programs will automatically show any images contained in the email.

I've just paid, but the AcceptEmail in my inbox does not show this yet. Why is that?
After you've paid, the AcceptEmail shows the new payment status immediately. To view this, open the email again or refresh your inbox. This way, you always know the current status of your payment.

Can I forward an AcceptEmail?
Yes, you can forward an AcceptEmail (showing the current payment status) just like any other email. An AcceptEmail cannot be paid twice. If anyone pays the AcceptEmail, the payment changes to green or “paid”, even in forwarded emails.
This means that someone else can pay the fee for you (e.g. your parents, university or employer).

Bank Transfer

If you do not have a credit card we can send you our bank details. Please note that all costs related to the fee transfer have to be paid by you. In the application form, please select "I will pay online (IDEAL or credit card)" and request for our bank details later on by sending an e-mail to with the header: "Payment by Bank Transfer".


If you have been nominated by your home university or Radboud Summer School to receive a scholarship or tuition fee waiver, we will send you a  coupon code by e-mail which you need to use when you apply online.
Please note that you cannot choose the scholarship payment method in our application form if you did not receive a coupon code from us.

We do not offer the option to pay by invoice. It is possible to get a receipt after the course fee has been paid. Please contact to request a receipt.
