The Quality Care Commission has this week reported an improvement in standards at Birmingham home Andrew Cohen House, which received the lowest QCC ranking, "inadequate", after a February inspection.
But although the QCC accepted that the home had "taken appropriate actions to meet the legal requirements we looked at," it still "requires improvement".
The commission first raised concern over standards at Andrew Cohen House - the only Jewish home in the Midlands - last July.
In the February inspection, the QCC found that "the provider had breached the Health and Social Care Act 2008 in relation to the care and welfare of people, safeguarding people from abuse, management of medicines, staffing, supporting workers and assessing and monitoring the quality of the service".
Two warning notices were subsequently issued and the home was prohibited from taking in new residents - there are currently 42 at 59-place facility.
It's been a difficult patch but we've put it right
This sanction has been lifted with the latest ranking, the home having hired specialist consultancy Redwood Care to help effect changes.
Andrew Cohen House is administered by Birmingham Jewish Community Care, where trustee and former Birmingham Lord Mayor Sir Bernard Zissman said it had been "a difficult period". But he believed the home was "back on track" thanks to the efforts of staff and Redwood Care.
Jules Gregory, commissioning manager for Birmingham City Council, said the home had dealt with its problems "swiftly and decisively.
"They were absolutely up-front with everyone. Once failings were exposed they very quickly acted to change."
The problems identified had "affected the culture of how staff were behaving in the home but they took a very responsible approach to it and now they're on the up".
Sir Bernard wanted the home to "get back to excellence, which we had enjoyed for many years.
"It's been a difficult patch but all organisations hit those. The question is what you do when you hit that.
"Do you pack up and go home or do you put it right? We've put it right."
