PSYCHOLOGIST recommendations that the victim and perpetrator of an alleged sexual assault in a public school should be assessed before returning to classes were ignored by the Education Department, the victim's father says.

Instead, the school produced a complicated plan for the girls to remain at the same campus.

The plan, seen by The Advertiser, shows the lengths teachers would have to go to to keep the girls apart.

In March 2010, a then 11-year-old girl was allegedly sexually assaulted by another female student at a Hills school.

Police investigated the incident but no action was taken. The alleged perpetrator was suspended and the school developed a detailed plan to keep the girls apart when they returned to classes, including:

ASSIGNING them separate areas of the schoolyard and keeping them apart during physical education activities.

REQUIRING they seek permission before moving between classes or going to the toilet.

REQUIRING teachers regularly communicate with each other about the girls' location.

ROSTERING an extra staff member to monitor the alleged perpetrator if both girls attended out-of-school-hours care at the same time.

In the case of lessons where classes joined together, the alleged perpetrator was to "move into class without making any contact" with the victim and sit at the front "with her own class".

The victim's parents, who ended up removing their daughter from the school, sought the advice of a psychologist who wrote, in a letter seen by The Advertiser, to the school's principal recommending "both students involved in an incident involving physical assault of this nature should be provided with psychological assessment and therapy".

The Education Department did not answer questions put by The Advertiser about whether this was done or if it is department policy to undertake psychological evaluations in such cases.

Opposition education spokesman David Pisoni said that the Education Department was "reluctant to take advice from outside experts".

Meanwhile, Premier Jay Weatherill - a former Education Minister - yesterday took a swipe at the department, saying he is sick of "a number of errors" it is making in handling the school sex abuse cases revealed in the media.
