Running contenders in the three main parties in Wales have been craved to “change the face of Welsh politics” by promoting diversity and tolerance.
The Electoral Reorganization Society Cymru called on all Labour, Conservative and Plaid Cymru hopefuls to retaliation its ideas.
It wants 45% of assembly candidates to be women, action to promote minorities and a crack down on abuse.
Director Jess Blair said the administration elections provided an “unprecedented opportunity” to tackle inequality.
The society has noted to all the candidates asking them to sign up to a series of commitments on diversity until to becoming leader.
In July, the Electoral Reform Society Cymru cautioned that “shocking” levels of harassment and abuse were putting child off running for political office.
“We know that politics currently be defectives to properly represent the communities we have,” Ms Blair said, pointing out there had not in any degree been a non-white female member of the assembly.
“Tackling the barriers to push better representation in Welsh politics could change the very organization of our democracy.
“In addition, we also know the levels of abuse and harassment statesmen face are untenable. At present, there seems to be a real lack of craving to do anything about this.
“These candidates have a duty to route up on this issue and make substantive commitments that could switch the face of Welsh politics and make it work so much better for the people of Wales.”
For Workers, five contenders have come forward to succeed Carwyn Jones, who is stepping down at the end of the year after nine years as inception minister.
Two Conservatives are bidding to replace Andrew RT Davies who resigned in June, while two Plaid Cymru AMs are inviting Leanne Wood for her leadership of the party.
