The country's bishops discussed the powers and structure of the planned commission at their three-day plenary meeting in Warsaw.
However, the guidelines proposed by Archbishop Wojciech Polak, who is responsible for the protection of children and young people, were not adopted.
Polak said on Friday that the preparatory work would continue.
The Legal Advisory Council of the Bishops' Conference had previously rejected the proposed guidelines.
The reason given was, among other things, that the material collected by the review commission could also be used for civil lawsuits against church organisations.
The guidelines for the commission are now to be revised again, according to the Bishops' Conference: "A number of comments have been received on the commission project submitted, which will be forwarded to the team working on the organisation of the commission." Further consultations with the religious communities are also required.
Chairman of the Bishops' Conference calls for "purification of the Church"
The Polish Bishops' Conference announced in March 2023 that it would appoint an independent team of experts to investigate cases of abuse from the period since 1945.
At their plenary meeting, the bishops emphasised that the commission was necessary. It should carry out a historical and interdisciplinary analysis, emphasised Bishops' Conference Chairman Tadeusz Wojda: "There is absolutely the will and the desire of all bishops to implement this and to carry out a cleansing of the Church in this regard."
The Legal Advisory Council had also expressed concern that the commission could summon bishops and pass judgement on them, although only the Vatican is authorised to do so.
The planned committee would also not be allowed to work together with people who do not have the good of the Church at heart.
Another objection is that it is unclear how much the commission's work will cost.
There is probably no other country where the Vatican has recently imposed disciplinary sanctions on so many bishops for neglect of duty in connection with allegations of abuse as in Poland.
Among other things, ten mostly emeritus bishops were ordered to pay money to a church foundation that supports preventative measures against sexualised violence against minors.
In addition, a number of bishops are no longer allowed to take part in any public church services.
