The school was slammed last year by HM Inspectors amid allegations of physical and emotional abuse. David Scott, the former principal, was forced to resign.
Edinburgh, the main provider of pupils to the part residential school, has worked with the new principal, Janet Allen, to tackle HMI's far-reaching recommendations. The school is financially supported by the Scottish Office which awarded a pound;1.2 million grant before the storm broke.
Fiona McLeod, head of quality services in the city, said: "We are pleased at the progress and there are many interesting new developments." The city has lent support with guidance, health and social education, mathematics, English language, monitoring and evaluation, and personal safety.
A key part of the overhaul has been the provision of three in-service days on child protection for all staff. New procedures and complaints systems are in place.
