I thank God for the missionaries who have survived the challenges of cross-cultural ministry and have a long-lasting impact on the work for Jesus. I am also grateful for those who invest in preventing the loss of missionaries from the mission field.

Having been a product of missionary attrition, I researched the subject extensively when writing Pre-Field Orientation and Training of FGM Missionaries. The preventable factors of missionary attrition were a significant factor in developing my system for equipping missionaries for cross-cultural ministry.

Many missionary candidates have insufficient theological education, ministry training, ministry experience, or spiritual maturity. This creates a need for pre-departure theological, spiritual and ministry training. Others may leave for the mission field overconfident with unrealistic expectations and ultimately leave their missionary career because they were not adequately prepared for what awaited them. (Brynjolfson 2006, 9)

Missionary attrition results in significant resource losses, creating sustainability issues for missionary work. According to Taylor (1997, 9-13), the attrition rate among evangelical missionaries in the late 1990s was about 5.1% per year, 71% of which was preventable. That means the attrition of more than 5,000 missionaries per year may have been prevented, either by more thorough screening or by better training.

The findings in the data from the ReMAP research project indicate that a large investment by mission agencies in missionary candidate selection and pre-field training is necessary for reducing the preventable attrition rate. (Blocher and Lewis 1997, 117)

Much of the current literature on missionary attrition is written about or in response to the World Evangelical Fellowship’s (WEF) study, the Reducing Missionary Attrition Project II (ReMAP II). This study included data solicited from 598 agencies headquartered in 22 countries. The ReMAP II report ranks 26 reasons why missionaries leave mission service (Brierley 1997, 92). While reasons like retirement, health problems and elderly parents may not be preventable, Bloecher (2005), Hay (2006) and Van Ochs (2001, 2005) indicate that, better screening, training and shepherding during the selection and preparation process may have helped to prevent other reasons for missionaries leaving service (e.g. problems with children, conflict with peers, personal concerns, or poor cultural adaptations). Blocher (2005, 2-4) quantifies the correlation between a lack of training and higher missionary attrition.

Concerned with financial losses due to attrition, secular multi-national entities (MNE) have also studied the problem of attrition of overseas personnel. Experts report attrition rates of 16-70% among expatriates with 50-70% of expatriate managers serving overseas returning early or under-performing due largely to a lack of training and preparation (Harrison 1994, 17; Ko and Yang 2011, 158; Osman-Gani and Rockstuhl 2009, 277).

Attrition and under performance of expatriates cost secular MNEs as much as $250,000 to $1 million (Littrell and Salas 2005, 307) or $2 billion collectively each year (Ghafoor 2011, 338). It can be assumed that the costs for overseas MNE attrition may be proportionally equal to overseas missionary attrition. As stewards of kingdom resources, churches, mission agencies and missionaries should be concerned about the financial losses resulting from missionary attrition and ineffective ministry.

Sometimes a lack of cross-cultural understanding on the part of the worker or missionary contributes to preventable attrition. Gannon (2011, 4) says, “… [H]umans compare a new and uncertain situation to something with which they are thoroughly familiar in order to understand it.” If the familiar is not similar to the new and uncertain, misunderstanding results. Living and working in a cross-cultural environment complicates individual life, family life and work.

It is easy for the expatriate or missionary to think he or she is behaving correctly or communicating effectively when sometimes the hosts are simply being polite or seeking to gain something from the visitor.

This lack of understanding and familiarity leads to stresses that can be overwhelming. Some of the stresses of serving in a foreign culture can be addressed biblically, but effective cross-cultural ministry also requires an understanding of the customs, thinking and beliefs of the host culture (Elmer 2002; Taylor 1997).
