Application process


Summer School of Science is open to all high school students with a strong interest in science, regardless of nationality. University students will not be accepted.

IMPORTANT: It is NOT necessary to have any previous research or science competition experience in order to attend. In fact, students who didn't have a chance to gain similar experience are especially encouraged to apply.


You can apply only by filling in the online application form. When filling out the form, you will need to upload a motivation letter and provide us with contact information of one of your teachers (not necessarily in the science field). If needed, we will contact your teacher separately to obtain a recommendation letter. In case you will be applying for scholarship (see below), you will need to upload a separate Scholarship application letter as well.
Incomplete applications will NOT be considered!

Application opening: March 20th 2021
Application deadline: July 1st 2021 at midnight (00:00 CET)

Summer School of Science is organized in two camps: S3 (for grades 9 and 10) and S3++ (for grades 11 and 12).

S3 2021: July 25th - August 4th
S3++ 2021: August 5th - August 15th


All applications will be reviewed by the school organizers and a certain number of applicants will be selected for interviews. Please, check regularly your e-mails to ensure that you got the response. We will let you know about outcome in both cases, being selected or excluded from the interviews. The advantage is given to students who can benefit the most from the School (eg. they have never participated in something similar before), since usually there are more good applicants than available places. Therefore, it is of great importance to write a good motivation letter! Interviews will be conducted by Skype, this year mid June. Students will be notified by e-mail about the exact time of the interview. During interviews, we focus on wide range of topics (not necessarily science), assess student's proficiency in English and his/her personal motivation. Final selection will be announced in the following week.

We believe that each applicant who has expressed an interest in science should be given the opportunity to develop professionally. However, due to lack of resources, we cannot place all interested students in one of our camps. Therefore, if you were not selected, it doesn't mean you were not good enough and you can always try next year. We still want to maintain contact with you and to offer you guidance when neded. Please visit the Summer School of Science Facebook page. There you can communicate with us, ask questions about science and careers in science, and be informed about many science-related events.

Fees and scholarships


The fee covers the licenses for software which will be used during the online version of the Summer School of Science. Since we are determined to make the experience as interactive and fluid as possible, we will be using professional software. It is also a very secure way of guaranteeing a safe and intuitive environment for our participants. Additionally, every project requires different software, which they will use during the Summer School to conduct experiments, analyze data and present the results.
The fee in the year 2021 is:

50 EUR

To help pay the fee, we encourage students to find a sponsor (your school, town or a company; international applicants can also try their embassy). There are several scholarships available each year. Please see the text below for more information.


Every applicant can apply for a scholarship, in which case you will pay the reduced fee of 20 EUR.

To qualify, you must include a separate letter in your application, explaining the economic situation of your family. This year we are able to give several scholarships to students who need them the most. A few scholarships are provided by the Society for Out-of-Frame Education.

Additionaly, as of 2018 Dominik "Dino" Knežević Scholarship is also available this year for several students. The priority is given to students of Matija Mesić Gymnasium in Slavonski Brod, Croatia. In case there are no successful candidates from that Gymnasium, it will be awarded to other students from Croatia or abroad, according to the criterion of need. You can find more details here (in Croatian).


Finding a sponsor can seem like a daunting task, especially if you have never tried it before. However, it can provide a lot of benefits. You will get training in fundraising, an important skill for students and scientists, who often have to find financing for their projects, studies or travel to conferences.

In order to find a sponsor, consider both big and small, local, national and international companies. Examples are: banks, state or private companies (especially those which benefit from research and development, like those in the pharmaceutical industry), government structures (schools, your city or county, embassy) or non-governmental institutions. Some of them give donations on a regular basis with competitions with fixed deadlines. In your request, you should include a one-page letter explaining your demand and why the School would be good for your education and career. Include the reasons why you are applying to them. We encourage you to add your CV and a Letter of Support, which we can send you.

If you have any questions, don’t hesitate to contact us. We wish you the best of luck! And remember - even if you are unsuccessful, you have gained an important experience.

How to write a motivational letter?

The principal aim of Summer School of Science is to gather people with professional interests in science and technology, and to provide them with practical experience according to our possibilities. Since only about 40 participants can be admitted each year (around 20 per camp), the organizers select those students who will benefit the most from participation. During the selection process, they will examine each student's background and motivation through the motivational letter and a Skype interview. Thus, it is of uttermost importance to write a good motivational letter, explaining your future goals and interests. The letter is a way for the organizers to get to know you and understand the reasons why you want to participate.

Your motivation letter should include:

  • Description of your own interests in science and how you express this interest
  • A short summary of your educational experiences, practical experience in science and opportunities you have used so far to expand your education (Note: It is NOT necessary to have any prior research experience or participation in science competitions.)
  • Plans for your professional development (i.e. choice of university, if you made it) and what actions you plan to take in the following years to develop professionally (in addition to applying to this camp)
  • Possible ideas of how you can help others with similar interests
  • Any other thoughts, ideas or interests you have that are important to you but not related to science

The letter should be at least 200 words long, but it can be as long and you want.
Finally, don't be afraid that you will write something "wrong". Honesty and openness are very much appreciated.
