According to a note from the National Maritime Authority, the ISN decided to extend the validity of lifeguard certification until December 31, 2024, with "all lifeguard cards that expire on January 1, 2024 being considered valid until December 30, 2024".

According to the organization, the measure is also applied "to additional modules to the lifeguard course".

As a certifying entity for the professional activity of lifeguard, ISN will carry out Specific Technical Aptitude Examination (EEAT) sessions for the purposes of recertification in the categories of lifeguard and lifeguard coordinator.

According to ISN, these sessions "are the only way for lifeguards to ensure the recertification of their cards without having to attend new training", as well as foreign lifeguards who wish to have their training recognised in Portugal.
