Applications and selection

Eligibility to apply

We are committed to achieving an inclusive and stimulating environment at our schools, and we encourage all qualified persons to apply. Applicants will be considered regardless of nationality, gender, age, ethnic origin, individual differences of belief, sexual orientation, or disability.

The school is aimed at postgraduate (i.e. minimum of Bachelor degree or equivalent) students, engineers and scientists with a few years' experience in particle physics, in computing, or in related fields. We welcome applications from all countries and nationalities.

Students who have attended any previous main CERN Schools of Computing, and who are interested in deepening their knowledge on the theme of this Thematic CSC, are also welcome to apply.


To apply, please fill in the application form and provide the requested information.

In order to login, you may use a CERN account, an EduGAIN-enabled account, or a public service account (GitHub, Google, Facebook or LinkedIn account). Alternatively, you can create a CERN lightweight account, and then login with your email ("Guess access"). You will also need to create an Indico account during the application process, if you do not already have one.

Applicants should ensure that they have:

  1. completed the application form online, and
  2. uploaded a signed formal letter of reference (on formal headed paper from the applicant's institute/organization) from their professor or supervisor.
  • If your professor or supervisor does not wish to provide you with a letter directly, s/he can email us your letter of reference instead. This should be sent directly to Computing.School@cern.ch, with the subject: Reference Letter tCSC 2023: [name of applicant]

The letter of reference needs to be received by the school (whether uploaded or emailed) by Monday March 13th 2023 (midnight CET) at the latest.

If no letter is included, the application will be considered void and discarded from the selection process. It is your responsibility to ensure we receive it.

Selection of participants

The number of participants is limited to 30. 

The participant selection is done by members of the CSC Advisory Committee, and is based on the profile and the motivation of the applicants. The goal is to select participants who have enough education and work experience to profit fully from the school, and for whom the academic programme of the school is relevant to their work or research. 

Applicants will be informed of the selection decision by Tuesday April 3 at the latest.

Selected applicants will receive an invitation to attend the school. Payment of the registration fee will confirm your place, at which point you will be considered a participant.


Participants must have health and accident cover that includes adequate protection (including emergency medical treatment, hospitalisation and repatriation in case of illness or accident), and against disability or death resulting from illnesses and accidents, for the country in which the school takes place. This insurance must also cover cases related to Covid-19 pandemic.

Participants shall hold CERN free and harmless from any cost or expense resulting from the situation where adequate insurance cover is not in place.


How to get there

See http://www.medils.org/contact under the "Where are we" and "How to reach us" tabs for transport links.


Participants should arrive at the MEDILS conference centre for on-site registration during Sunday 11 June 2023. If possible, participants should arrive as early as possible, the Welcome session will start at 16h, followed by a visit of Split old town and welcome dinner in the evening.

Participants are responsible for obtaining a valid visa to enter the country of the school location when this is required. The cost of a visa is not included in the school fee.

Accommodation and Meals


Participants will be housed in the MEDILS conference centre, or in a nearby hotel. Depending on their preferences, participants will be accommodated either in single rooms, or in shared (twin) rooms, with private bathrooms. Room allocation for shared rooms is done by the school organisers, with the aim of bringing together participants with different backgrounds and profiles.

Accommodation from June 11-17 is included in the School fee.

Smoking is banned in the entire conference centre.


All meals are included in the School fee. The first meal will be the lunch on Sunday 11 June for those who have already arrived, and the last meal will be breakfast on Saturday 17 June.

Participants should note that breakfast on Sunday 11 June is not provided, only the lunch and evening meal.

All food onsite at MEDILS is served as a buffet, while the special meals out are at local restaurants.

We will ask you in your application form about any specific dietary requirements you may have, and do our best to accommodate accordingly, given the local catering options available. However we cannot make any guarantees. 


Organizing the school in an environmentally responsible way is one of our goals.

During the school, we will:

  • Serve meals and drinks with washable plates, glasses and utensils; or with recycled and/or biodegradable ones
  • Have vegetarian and vegan dishes available as an alternative to dishes based on meat
  • Limit the amount of printed materials (and in particular, only provide the printed version of the school booklet to those who want to have one)
  • Separate and recycle waste

Please help us:

  • Consider traveling to school by train, bus, ferry, or any other less polluting means of transport, if possible
  • Bring your own reusable water bottle or cup
