A century after it was founded in response to the Titanic disaster, the London Nautical School is celebrating an improved Ofsted rating.
Two years ago the boys' secondary school in Stamford Street received a 'requires improvement' rating from the education watchdog.
Now a new inspection report has rated the school as 'good' – the second highest grade available.
According to the report: "School leaders, well supported by the governing body, have acted quickly and effectively to address the weaknesses identified by the school's last inspection. As a result, the quality of teaching, as well as other aspects of the school's work, is now consistently good."
In a letter to parents, headacher Hyder Dastagir wrote: "This is a wonderful outcome for the school and I know you will understand what it means to, and for, every member of the LNS community.
"It confirms what we always knew to be true. The London Nautical School is a place with an outstanding team of staff that works with passion and commitment to provide high quality learning experiences for a wonderful pupil body who want to learn, are proud of their school, and are well-mannered and confident.
"Running through the entire report is recognition that it is a very special institution that offers students opportunities unmatched by any other."
The London Nautical School was founded in 1915 in response to recommendations made in the official report into the sinking of Titanic.
Originally located in Rotherhithe close to Surrey Docks, it moved to Waterloo in 1965.
The Ofsted report also notes that the school's "unique expertise in nautical education and training makes a significant contribution to students' preparation for further study and future employment".
Despite its Ofsted success, the school received a rating of 1 on a scale of 0 to 5 in a recent food hygiene inspection.
