Missionary attrition refers to the premature return of missionaries from the field. Studies show that the majority of early departures stem from preventable issues such as:

• Poor conflict resolution or team dynamics
  
  
• Financial instability or support fatigue
  
  
• Culture shock and emotional exhaustion
  
  
• Lack of spiritual and practical preparation
  
  

The good news is that missionary attrition can be dramatically reduced with the right kind of training—training that prepares workers spiritually, emotionally, and practically before they ever step onto the field.

For more than two decades, Global Frontier Missions (GFM) has been helping missionaries not only go—but stay—through biblically grounded, field-tested training programs.

Here’s how GFM tackles the very challenges that cause most missionaries to leave.

GFM’s Missionary Training School (MTS) and Online Missionary Training School (OMTS) are designed from over 20 years of cross-cultural experience.

Graduates now serve among unreached people groups around the world, planting churches and building long-term ministries that last.

Unlike short-term mission trips, GFM’s programs equip participants for the realities of life and ministry overseas—spiritual warfare, language learning, teamwork, and sustainability.

At GFM, training integrates theology and practice so that missionaries are equipped to thrive in every dimension of ministry. Students learn how to:

• Communicate the gospel effectively across cultures
  
  
• Work through conflict and diversity on international teams
  
  
• Develop rhythms of prayer, rest, and resilience
  
  
• Create long-term strategies for sustainable impact
  
  

This holistic approach transforms passion into perseverance.

Instead of reacting to crises on the field, GFM prepares missionaries to avoid them through proactive training in:



• Conflict resolution and teamwork – minimizing burnout and division
  
  
• Support-raising and stewardship – ensuring financial stability
  
  
• Cross-cultural immersion – helping trainees adapt in a safe environment before deployment
  
  

When missionaries understand what to expect and how to respond, they’re far more likely to stay long-term.

Not everyone can pause their life for months of residential training. That’s why GFM offers two flexible pathways:

• Missionary Training School (MTS): A five-month, in-person community experience designed for deep growth and discipleship.
  
  
• Online Missionary Training School (OMTS): A fully remote option that allows you to prepare from anywhere in the world.
  
  

Whether you’re a student, parent, or working professional, there’s a program that fits your situation.

GFM is more than a school—it’s a launching platform.

Graduates are connected with sending agencies, churches, and partner organizations ready to mobilize them into long-term cross-cultural ministry.



The mission doesn’t end with training—it begins there.

Missionary zeal is powerful, but preparation is what sustains it.

If God is stirring your heart for the nations, don’t let lack of preparation cut your journey short.

Through Global Frontier Missions, you’ll be trained, supported, and connected for lasting impact among the unreached.
