The government is yet to deliver about one in five of the proposals in Labor and the Greens' power sharing agreement, inked after the 2016 territory election.
But 89 items have been ticked off the list, including a ban on property developer donations to political parties, and extra school psychologists.
The parliamentary agreement - which guaranteed The Greens' supply and confidence in the Andrew Barr government - was signed in October 2016.
Among the items which have not been delivered is the expansion of the lobbyist register, with the Legislative Assembly determining it would not occur this parliamentary cycle.
The deal had also asked the government to complete a feasibility and business case for a new Canberra convention centre - the Australian Forum.
But the government did not complete the work, saying it was a longer term infrastructure priority.
The agreement said the government should conduct a review of the effectiveness of the Energy Efficiency Ratings Scheme, however this is yet to be completed.
Plans to construct purpose built accommodation for people experiencing mental health concerns and housing difficulties, using the MyHome for Canberra project plan, have not been delivered.
The deal agreed the government should have signed contracts for light rail stage two before the 2020 election.
This is yet to occur, with the government blaming the delays on the COVID-19 pandemic.
Among the agreed priorities was that the government would establish a panel of independent auditors to conduct mandatory annual audits of building certifiers.
This is yet to be completed but is listed as "on track".
Some 89 key priorities from the agreement were delivered, included building three new walk-in centres, creating the ACT Integrity Commission, and achieving 100 per cent renewable energy.
A further 16 were listed as not completed but "on track", while seven were either delayed or not progressing.
Under the power sharing deal, Greens leader Shane Rattenbury was guaranteed a ministerial position.
In a joint statement from Labor and the Greens, the parties said they had worked together over the past four years to deliver an effective and stable government.
"Canberra is progressive, diverse and inclusive - and the government has ensured these values were reflected in the work progressed throughout the 9th Assembly," the statement said.
