According to report The Welsh Rugby Union was responsible for a "serious failure of governance" and missed opportunities to act on concerning behaviour within the organisation.
A committee of Senedd members noted "systemic failures in the culture" of the WRU following allegations of racism, misogyny, sexism and homophobia.
The issues first came to light in a BBC documentary which aired at the beginning of the year, after which the WRU announced an external taskforce had been set up to investigate.
Concerns female rugby players in Wales may have faced "unfavourable treatment" had been highlighted to the WRU two years ago in a review of the women's game, extracts of which were published on Friday as part of the Senedd report.
The WRU expects its independent review panel to report "before the end of summer" and welcomes the Senedd’s suggestion that an implementation plan should follow soon after.
