Park House has not employed an agency worker since autumn 2017.
In her report for last week's Scrutiny Committee meeting, the Council's Senior Manager for Services to our Community Aisling Khan said that the quality and quantity of applications for the residential home has "changed dramatically".
She wrote: "Between 2015 and 2017 6/12 the service advertised 52 times, often with no response. Advertisements now attract a choice of applicants and we are also seeing informal enquiries about opportunities."
Aisling told Members at the meeting: "We're doing a huge amount of training in the team. Seven people went through NVQs. How I think you make things sustainable on Scilly is that you create career prospects that are interesting. So before when we went out to recruit a Registered Care Manager we are not necessarily marketing a highly interesting career and actually it sounds all a bit stressful.
"What we can now sell is a really really strong job offer. 'Come and run a great care home on the Isles of Scilly where we are developing new models of care for the future'... You're selling something that is attractive."
She also revealed in the report that since April 2017, Park House has gained 10 new permanent members of staff including the Registered Care Manager, while six members of staff have left their permanent roles. However, two of those are now employed as casual staff and there are also two new members of casual staff.
The report added: "We are currently recruiting for a new Catering Assistant and around 70 hours of care. In the assessment and planning team we have recruited three new members of staff - two new social workers and administrative support."
Park House was rated ‘Good’ in the latest report from Care Quality Commission (CQC) inspectors.
