The school had previously been judged to require improvements, but inspectors rated it Good across the board following an inspection at the start of May.
In their report now published, they found that pupils 'wholeheartedly live by the school rules of "be respectful, be safe, be ready to learn".
Pupils enjoy attending the Caledonia Road school, have positive attitudes to their learning and benefit from caring relationships between pupils and staff which are underpinned by kindness and mutual respect.
The school’s Catholic foundation permeates throughout school life, with all pupils invited to start the day with a prayer. The school welcomes many pupils from different cultures and faiths, and is inclusive and diverse, with many opportunities to celebrate international languages, religious festivals and different cultures.
The school has designed a 'structured curriculum' to build what pupils will learn from the early years through to Year 6, with staff using 'a range of exciting tasks to capture pupils’ interests in lessons' and helping them 'make links between their learning and build on learning over time'.
The school is determined that every child will become a confident and fluent reader, and 'achieves this well'. Pupils who struggle to read are given extra support, helping them 'read with increased confidence and fluency', while advanced readers are given further support to enhance and deepen their reading skills.
Pupils with special educational needs or disabilities (SEND) are accurately identified, with the school working closely with families, external agencies and the child to develop strategies that will support the pupil to learn. As a result, 'pupils with SEND progress well.'
The school’s personal, social and health education (PSHE) is 'well planned and sequenced', all of which 'helps pupils to make the right choices and know how to contribute positively to society'.
Pupils also have many opportunities to take up leadership roles in school, with 'ecowarriors’ working to reduce the use of plastic in school, ‘reading champions’ helping their peers to select books to read, and ‘school councillors’ organising charity fundraisers, enabling them to play an active role in their community.
Inspectors judged the overall effectiveness of SS Mary and John’s Catholic Primary Academy to be Good, with each inspection area – the quality of education, behaviour and attitudes, personal development, leadership and management, and early years provision – also rated Good.
Principal Krystyna Bickley said: "I am incredibly proud of the children and staff and this report reflects the hard work of everyone, and the support of parents."
Toni Ellis, CEO of the St Francis and St Clare Catholic Multi Academy Company, added: “This is a significant step in the journey of a school that dedicates so much to nurturing pupils in the broadest sense. Pupils, staff and families deserve the best and we are grateful to all those who continue to contribute to securing the best standards of education for our children.”
Councillor Jacqui Coogan, the City of Wolverhampton Council's Cabinet Member for Children, Young People and Education, said: "This is an excellent report which demonstrates the progress that has been made at SS Mary and John's.
"Inspectors recognised that the school has been on a journey of improvement and were full of praise for Krystyna Bickley and the impact she has had since she joined. I would like to congratulate Krystyna, her team and all the parents and pupils on their success."
Latest figures show 92% of schools in Wolverhampton are now rated either Good or Outstanding, above the regional and national average. In addition, more than nine in 10 Wolverhampton pupils attend Good or Outstanding schools, the best in the West Midlands.
