Haredi and the vast majority of Modern Orthodox Judaism has a blanket prohibition on women leading public congregational prayers. Conservative Judaism has developed a blanket justification for women leading all or virtually all such prayers, holding that although only obligated individuals can lead prayers and women were not traditionally obligated, Conservative Jewish women in modern times have as a collective whole voluntarily undertaken such an obligation. Reform and Reconstructionist congregations permit women to perform all prayer roles because they do not regard halakha as binding.
