The Clore Social Leadership Programme has begun accepting applications for its 2016 course, which starts in January.
The programme, which was set up by the Clore Duffield Foundation to improve leadership in the not-for-profit sector, will be taking on up to 20 new students.
The 2016 course will feature three new specialist fellowships focusing on gender equality, youth social justice and migrant communities.
The Clore programme can be completed either full-time over one year or part-time over up to two years.
Anybody working or volunteering for UK-based charities, social enterprises, housing associations, community organisations or cooperatives is eligible to apply.
Applicants must be able to demonstrate significant achievements and leadership potential in work already carried out and a commitment to the social sector in the longer term.
The course includes residential elements, a secondment and a practice-based research project.
Employers will receive bursaries of up to £15,000 to support them in releasing fellows for their time on the programme; people who are not employed are eligible for bursaries of up to £20,000.
Dame Mary Marsh, founding director of the programme, who is standing down in July after almost seven years in the role, said the application process was a developmental experience in itself.
"Applicants are challenged to reflect rigorously about themselves and their potential to progress as leaders of social change," she said. "Those who are successful in being appointed as fellows build on this by sharing their learning with each other and making the most of the individualised leadership development programme provided."
Marsh will be replaced by Shaks Ghosh, former chief executive of the Private Equity Foundation until its 2013 merger with the Impetus Trust. She also spent 10 years as chief executive of the homelessness charity Crisis.
Applications for places on the Clore programme must be received by midday on 25 June.
