A recruitment drive has seen 120 registered nurses appointed by Mid Yorkshire Hospitals Trust.
Trust bosses, who run Dewsbury, Pinderfields and Pontefract hospitals, said more than 100 healthcare assistants (HCAs) and 60 student nurses had also been appointed since last November.
And the recruitment included 44 jobs at Band One, an entry-level position for people who can go on to train as nurses or HCAs.
New staff were taken on after Mid Yorkshire was criticised for staffing shortages by the Care Quality Commission (CQC) last December.
The trust was rated “inadequate” for whether its services were safe by CQC inspectors who highlighted staffing problems and poor hygiene standards.
Mid Yorkshire said 50 of the new registered nurses would join the organisation between now and August.
Acting chief nurse David Melia said: “As a trust we are delighted to have seen such a great response to these positions and to have met such ambitious and inspiring people who want to become part of the team in providing quality care to our patients.
“I’m sure they will quickly settle on their wards, where we expect them to display the caring and compassionate qualities we rightly require to provide the highest standard of care possible for our patients.”
The trust said it would also be offering tailored training and mentorship packages to new employees, known as a preceptorship.
Each will be assigned a preceptor, or mentor.
Mr Melia said: “We will be offering all of our new recruits a great deal of support in their first few months with the trust and we’ll also be offering the Preceptorship scheme to all of our newly qualified nurses.
“We look forward to welcoming all of our new starters to the trust over the next few months.”
Mid Yorkshire could carry out a centralisation of A&E services six months earlier than planned following the CQC criticism.
Trust bosses believe care will be made safer by plans to downgrade Dewsbury’s A&E to an urgent care centre.
Life-threatening emergencies will be taken to an expanded A&E at Pinderfields Hospital in Wakefield.
The A&E move was planned for spring 2017, but has been brought forward to this September this year under new proposals.
Earlier implementation was also expected to save the trust £10m a year.
