In the last academic year there were just over 2500 incidents when a child was sent home from a city school because of their behaviour.
That is down from nearly 7500 such cases in 2006-2007 as teachers increasingly try to keep troubled and troubling youngsters in the classroom.
Attendance figures too are up across the board, at primaries and secondaries, meaning more children are spending more time learning.
Stephen Curran, the councillor in charge of children and young people on the city council's ruling cabinet, hailed the new figures.
He said: "With increased attendance, reductions in exclusions and attainment across the board at an all time high.
"Glasgow is constantly driving up standards in education and we are really starting to see the benefits.
"If our children are not in school then they are not learning.
"Parents can be assured that we will build on this success story and continue to raise standards across the city."
The number of pupils permanently expelled - removed from the school register - has dropped very significantly from a peak of 140 in 2006-2007 to just three in 2011-12 and four in 2012-13.
A paper before councillors today states the reason is because heads are now adopting a "more problem-solving approach to the management of young people with challenging behaviour".
The paper adds: "It is our experience that working positively with families and other agencies ensures more positive outcomes for young people."
Lower exclusions - along with fewer absences for illness and truancy - have helped to push up overall attendance figures for secondaries from 88.4% in 2007-08 to 91.2% in 2012-2013 for city secondaries.
The trend for lower exclusions, seen throughout Scotland, mirrors both declining youth crime and a change in tactics on dealing with those on the edge of trouble.
As The Evening Times Crime on Your Street series revealed this week, the number of offences committed by under-18s in Glasgow has fallen 45% since the change of government in 2007 and the end of the "War on Neds" policy.
Public complaints about young people in Glasgow have also plummeted.
Chief Superintendent Andy Bates, Glasgow's local police commander, said: "There is something different about the way we and other agencies deal with this generation."
