The Clore Social Leadership Programme will offer seminars, tuition, mentoring and secondments to 20 fellows each year.
Courses will be tailored to individual needs, and will include a two-week residential training programme.
The two-year programme was developed by the Clore Duffield Foundation and a 32-strong advisory panel, which included representatives from Acevo, the Big Lottery Fund, the NCVO and the Charities Trust.
The cost of each fellowship is estimated at £55,000, to which the foundation will contribute £15,000. A director will be responsible for raising the remainder.
"The sector requires top quality leadership," said Dame Vivien Duffield, chair of the Clore Duffield Foundation. "The foundation's proposal to identify emerging talent and combine it with bespoke, sustained leadership training will be a tremendous boost to the sector and to society as a whole."
