REDNOCK School has failed to improve enough in the last year but leadership and management is better, according to its latest Ofsted report.
Inspectors visiting the secondary school and sixth form in Dursley recorded the rating "requires improvement" again after not hitting targets in its quality of teaching or in the achievement of pupils after an inspection in December.
The Ofsted report, headed by lead inspector Chris King, did note behaviour among pupils and the leadership and management shown by staff were of a good standard and some improvement had been made.
"Despite improvements, too many students still do not make good enough progress from their starting points in year seven," he said.
"The least effective teaching has now been eradicated, but the overall quality of teaching over time has not been strong enough to drive students’ learning and progress at a fast enough pace."
The school has had three Ofsted inspections in two years after receiving a level three rating each time, with four being the lowest.
A school with level three ratings across all four subjects would need another inspection six months later.
Mr King did however highlight a number of strengths at the school, which has 1,370 enrolled pupils, including sixth formers.
"There are good systems and processes in place to check on the quality of the school’s work over time. There is a good range of training opportunities in place to help the school improve the quality of teaching and other aspects of its work," he said.
"Pupils’ behaviour is good and the number of exclusions has reduced greatly and there have been good improvements in students’ attendance.
"The headteacher has a clear and accurate view of the strengths and weaknesses of the school and is supported effectively by governors and is resolute about bringing about improvements, particularly in the quality of teaching," he said.
Headteacher David Alexander said that while there was still work to do he was confident the school was only going to get better.
"That there has been an improvement in terms of leadership and management is the significant thing," he said.
"Don’t get me wrong it is the same level so still there is a need to improve. Historical results weren’t good enough but things are now in an upward trajectory.
"We are now quite rigorous in ensuring that teachers' assessments of their classrooms is robust and we are now really sharp in getting to lessons and checking on how things are going, we are talking daily.
"We know where we should be and it didn’t feel like a report we should feel particularly unhappy about. We are on a journey and a good way along it."
