Rolleston Primary, in Eyres Monsell, is celebrating being awarded a "good" rating by Ofsted in every area.
The school, which was already deemed to be good by the education watchdog, was visited by inspectors last month (Nov). A full report has just been published.
Inspectors said that head teacher Dwayne Toon led the school very effectively and was well supported by senior staff in checking pupils' progress and teaching quality.
Mr Toon said: "We're extremely pleased to have been rated good by Ofsted in every single area we were inspected in. This is testament to the hard work we put in every day to ensure that every child who attends Rolleston gets the most out of being at school. We're committed to helping all our children to achieve."
Inspectors said that pupils' experienced a good range of activities and their behaviour was good.
Good teaching was praised and the report said that staff were keen to improve even further and readily accepted advice and extra challenge.
In addition, the school was said to work well with parents and families, and as a result, attendance had risen significantly.
The school's "happy environment" was also highlighted, as was pupils' spiritual, moral, social and cultural development.
To improve even further inspectors said that aspects of writing still needed to improve and pupils should be given more opportunities in science to investigate for themselves or use their maths skills to interpret results.
The school was visited this morning by Councillor Vi Dempster, assistant city mayor responsible for education, along with ward councillors Rory Palmer and Virginia Cleaver, who congratulated staff for their efforts.
The school's last full inspection was in September 2009 when it was rated "good" in most areas and overall.
Councillor Dempster said: "This result is a credit to Rolleston and to the teachers, families and governors who together make this school such a welcoming and productive environment for the pupils.
"I congratulate the school, and I'm delighted that the local authority's work in partnership with schools like Rolleston helps to produce such positive results."
Fellow ward councillor Virginia Cleaver, who is also vice-chair of governors at Rolleston, said: "Rolleston provides a fantastic education for local children. I'm delighted to be able to help them celebrate this result."
