In a review of the region's Children and Family Court Advisory Support Service published this week, Ofsted inspectors said records of cases were still not consistent.
Inspectors also raised concerns that proper analysis of the needs and risks facing children was not evident in recordings of interviews.
The report criticised the service for being guided by "practitioners' personal preferences" rather than a common assessment framework.
It states: "The assessment framework is not in place and Cafcass acknowledges that service users are still not consistently informed of the content of reports."
But the report praised the "good" progress made in ensuring that staff respect the privacy and dignity of families. In the previous report inspectors had raised concerns that confidential information had been shared with schools and unnecesarily included in reports.
The review also found "satisfactory" progress had been made to improve safeguarding checks of children, provide user-friendly information for children and adults about the family court process and improve the complaints procedure.
Anthony Douglas, chief executive of Cafcass, accepted some of the findings. But he criticised Ofsted for not giving enough consideration to the pressure facing Cafcass practitioners, with increased workloads in certain areas of South Yorkshire, particularly Doncaster.
He added that he was satisfied with internal quality assurance checks with case records.
He said: "It has been an extremely difficult year with practitioners under huge pressure from increased demand. Improvement work is hard to maintain with so much work going in to managing the high volumes of work coming in.
"Of course there is a long way to go but our improvement plans are on target."
Published in July 2008, the Ofsted inspection of the experience of Cafcass users in the family courts in South Yorkshire recommended improvements in:
* the quality of case planning and recording
* meeting timescales and informing service users of any delays
* a transparent common assessment framework
* safeguarding practice
* the quality of private law reports
* information provided to children and adults
* respect for the privacy and dignity of service users
* the quality of information given to service users when making complaints
* the timeliness and quality of response to complaints
