The new Union of Jewish Students chair has pledged that the organisation has "a new purpose and mission".
Adam Pike, who took up his role on July 1, said this week he had already implemented wide-scale changes in an attempt to rejuvenate the union.
Last year, the JC revealed how an internal review attacked UJS for lacking "a clear and focused sense of mission, role and purpose" and for having "serious logistical, administrative and management deficiencies".
The review said relationships between the union and some Jewish societies had broken down and recommended closer interaction with individual J-Soc chairs.
Dan Hunter, a former co-president of Nottingham J-Soc, resigned, blaming the union for failing to push resources towards smaller societies at universities such as Warwick and Leicester. Others thanked the union for providing educational programmes and supporting Friday-night dinners.
Mr Pike, 22, said his work had begun with the restructuring of the UJS central office, with the traditional fieldworker roles replaced by national officers mirroring positions on local J-Soc committees.
Three new development officers in the north, south and central regions will now work more closely with J-Soc committees which have fewer members in an attempt to offer them more regular assistance.
He said: "We will be focusing a lot more on face-to-face contact with smaller J-Socs."
New events will include a Purim carnival held in central England, a summit in December which will train newly-elected J-Soc committees, and social and educational programmes on campuses.
Students will also receive greater benefits if they hold UJS membership. A careers-advice service will be launched alongside other campus schemes.
