Categories Of Field Workers

Mission Partner

These include all our personnel wherever they may be based, but excluding trainees, interns, and certain office administrative staff.

Other “special” categories of Mission Partners are as follows:
• Mission Partner Professional – a person working for a service or business organisation in a cross-cultural
situation with the purpose of being active in Christian ministry.
• Mission Partner Seconded OUT – a person released by WO to work under the supervision of another mission agency, organisation or church.
• Mission Partner Seconded IN – a person seconded by another mission agency to serve in the field with WO.

Mission Associate

A person who has an existing ministry within their own country who is joining WO through a relational pathway which normally progresses from Mission Friend to Mission Associate to Mission Partner. This is a time-based progression depending on joint agreement.

Alternately this is a person who has had a long-term relationship with WO and/or because of unusual circumstances, is endorsed to function outside of the normal administrative requirements of WO. Such persons are warmly regarded as members of the wider WO fellowship.

Short Term Worker

A person who is serving with a WO Mission Partner for a period of three to twelve months.

Mission Intern

A person who is a prospective Mission Partner and who has linked to WO for a specific period of time (normally 6-24 months) in order to receive training and practical field experience under the supervision of an experienced Mission Partner.

Alpha Mission Team member

A person who is part of a church planting team in a UPG undergoing two years of on-the-job training.


A person preparing to serve cross-culturally who is undergoing a period of guided preparation, study and service through mission trips.

Team Member

A person directly accountable to a Mission Partner who is responsible for all aspects of their ministry, pastoral care and financial support. A Team Member is considered to be part of the wider WO fellowship because of their accountability to a recognised WO ministry. They are normally working in their own culture or country.

Each category has slightly different services and conditions. The key definitions, and main services offered by WO to the different categories of field workers are listed in the Operations Manual. These include e.g. regular member care visits, and publicity. The main requirements of WO e.g. payment of 10% mission’s contribution on all donated income for Mission Partners are also detailed in the Operations Manual. You will be given the Operations Manual to read as part of your applications process.

Applicants will be guided as to the correct category to apply for in their particular situation and must familiarise themselves with those terms and conditions.
