The latest information revealed yesterdat on the My School website indicated Wellington Public School and St Mary's had good trends which pleased their respective principals.

Wellington Public School principal Denis Anderson said the raw data showed very good trends in many areas.

"Every graphic shows there is an improvement based on state averages," he said.

Mr Anderson acknowledges school attendance figures are improving but admits there's a way to go.

"We have an intensive program as we battle to get children to school and keep them. You can't learn when your not here," he said.

"We are conscious of the responsibility we have and that of parents to keep the children at school.

"Our new strategic planning model is almost complete on the care, relationships and curriculum and there are exciting things happening soon at the school. Our teachers are doing a great job."

St Mary's Catholic School principal Simon Price said a 93 per cent attendance rate was good but it took a lot of work and that with the assistance of others it was a good news story.

"We have tracking procedures in place and these help us monitor missing students," he said.

On the NAPLAN results year 7 numeracy is a shining result for the school numbers well above the state average.

"Many of the results are very pleasing, really satisfying," Mr Price said.

"The student gain is an important area to look at and it's very consistent. The strength of our school through years 3 to 9 is excellent."

Both principals say the recent visit by members of a group on Restorative Practice which looks at the impact of crime by young people has been a success.

"The leadership shown by all of our schools has been impressive and the way we have worked together shows we believe in the future of our town," Mr Price said. "All of the teachers are engaged with this program."

Mr Anderson agreed outlining the creative program was embraced by his teaching group.

NSW Education Minister Adrian Piccoli told schools they would need to detail to parents how they planned to improve their NAPLAN results, increase the proportion of HSC students achieving top marks and ensure teachers were maintaining high levels of expertise in their subjects.

Australian Curriculum, Assessment and Reporting Authority (ACARA) chief executive Robert Randall said the annual update of My School was eagerly anticipated by "mums and dads on soccer fields" and teachers and education policymakers but he warned it was only part of the overall picture of the school system.

"My School is about providing a common reference point for fair comparisons... we do not support simplistic league tables," Mr Randall said.

ACARA also released yesterday a study by research firm Colmar Brunton into parents' views of My School which will include recommendations to improve the site.
