Updated application instructions

What supporting documents should be attached to the application form? The rules for completing some sections of the application form have recently changed. Check this page for the latest guidance before applying.

Make sure that all supporting documents fully correspond to the information declared in your application form. Any missing, inconsistent or incorrect document may result in exclusion during the eligibility checks or in your application being declared ineligible.

General rules

You must upload a single PDF file, which must:

  • Include a table of contents listing each document in sequence
  • Follow the order set out below
  • Contain clear and legible copies of all documents
  • Be fully consistent with the information declared in the application form, in particular names, employers and institutions.

Dates:

The dates declared in the application form must match exactly those shown in the supporting documents.

Overlapping professional, international, or educational experiences are accepted only when no more than two experiences overlap and at least one of them is declared as part-time.

Declaring dates in the "Education" section:

  • Date of completion of diploma:
    Use the date indicated on the diploma or the final year of the study cycle.
  • Missing start or end dates:
    If the diploma does not indicate dates, enter:
    • the first day of the starting month and
    • the last day of the last month for the end
  • The period indicated must clearly represent a full academic semester or year.

Declaring dates in the "Professional" and "Internation experience" sections:

"Do the dates declared in your application form match exactly those in your supporting documents?" (question to be found in the application form): 

  • Select "Yes" only if the supporting document indicates exact dates including day, month and year. 
    Indicate this in the format DD/MM/YYYY in the application form.
    Example: 1st of May, 2020 or May 1, 2020, → 01/05/2020
  • Select "Yes" for on-going experiences when your supporting document indicates an end date after the closing date of the application period. Indicate the last day of the application period as the end date of the experience and calculate the duration up to that date.
  • Select "No" if the exact day (DD) is missing from the supporting document, even if the month and year correspond. 
    Indicate this in the format DD/MM/YYYY in the application form with the first day of the month as the start date and the last day of the respective month for the end date.

Professional experience

  • The minimum duration for an experience to be declared must be 15 calendar days. If your experience does not amount to 15 calendar days (in full-time employment equivalent, in case of part-time experience), it cannot be declared.
  • Only experiences accumulated after your 16th birthday are accepted.
  • Every experience must be declared separately if it is not continuous or if you changed the position within the same organisation.
  • Only full-time equivalent experience is accepted. One full-time workday is considered to be 8 hours.
    If you worked part-time, you must convert your experience to its full-time equivalent.

To convert part-time work into full-time days:

  • Calculate the total number of hours worked part-time.
  • Divide the total hours by 8 (the number of hours in a full-time workday).
  • The result corresponds to the number of full-time equivalent days (calendar days, including weekends and holidays).

One month of work at 50% of full-time is equivalent to 15 calendar days of full-time work.

Accepted types of experience

  • Work experience (paid or unpaid)

  • NGO or political party activities.

Not accepted

  • Recommendation letters, duly signed and dated (please introduce the exact dates as in your supporting documents)

  • Only experiences acquired after your 16th birthday are accepted.
  • Only full-time equivalent experience is accepted.
  • For experiences carried out on a part-time basis, the duration must be converted into its full-time equivalent. A full-time equivalent day corresponds to 8 hours.

To convert part-time experience into full-time equivalent days:

  • Calculate the total number of hours completed.
  • Divide the total number of hours by 8.
  • The result corresponds to the number of full-time equivalent calendar days (including weekends and public holidays).

Example:
One month of experience completed at 50% of a full-time schedule is equivalent to 15 calendar days of full-time experience.
