Rainbow Friday is a celebration of diversity held regularly in Polish schools. Rainbow Friday events have faced boycotts from right-wing politicians and activists in previous years. Among them, Barbara Nowak, former school superintendent of Małopolska, protested against the initiative, attempting to challenge its legality by publishing an official statement condemning Rainbow Friday on the superintendent's website. Additionally, Law and Justice MP Janusz Kowalski, then representing Sovereign Poland, sent a letter to headteachers in Opole, urging them to "protect children from harmful gender ideology" in response to the publication of the LGBTQ+ Friendly Schools Ranking.

Rainbow Friday aims to raise visibility for LGBTQ+ individuals and promote educational values. As part of the campaign, students and teachers are invited to participate in various activities, including workshops and lectures, as well as to decorate their schools with posters and symbols supporting diversity, such as flags representing sexual minorities or educational banners explaining the difference between sex and gender identity and promoting inclusive language. This year's nationwide Rainbow Friday will take place on 25 October, under the slogan "Let's Build Bridges of Diversity."

The GrowSPACE Foundation has reported that, for the first time, Superintendencies of Education have become involved in the Rainbow Friday initiative. In response, the ultra-conservative organisation Ordo Iuris has sought to counter Rainbow Friday by organising a competing event.

"The messaging that young people are exposed to during 'Rainbow Friday' could lead some of them to develop uncertainties about their own ‘sexual orientation’ or ‘gender identity,’ potentially disrupting their natural psychosexual development," states the Ordo Iuris website. The organisation has been inciting fear among parents and guardians, portraying the LGBTQ+ community as an "unnatural" and "destructive" influence.

"School principals are constitutionally required to respect the principle of parental educational primacy," commented Marek Puzio, senior analyst at the Ordo Iuris Institute. "Parents should be informed of any planned activities such as 'Rainbow Friday' at their child's school, and they have the right to refuse their child's participation." As part of its opposition, Ordo Iuris supports a concurrent event organised by the Centre for Life and Family, dubbed "Noble Friday."

Rainbow Friday aims to support students grappling with self-acceptance and feelings of uncertainty or misunderstanding from family or peers. The initiative seeks to improve the well-being of LGBTQ+ youth in Polish schools and beyond.
