PHASES OF
ENGAGEMENT
TOOLKIT
A shared, globally usable language for measuring gospel progress among people groups, from Waiting to Sustained Gospel Presence.
A collaborative framework developed by Frontiers, IMB, Joshua Project, Engage Network, Vision 5:9, and Accelerate, with input from practitioners and researchers around the world.
Motivations and Explanation
Why Something New?
For years, our shared language was mostly two data points: Engaged or Unengaged and Christian/Evangelical %. Helpful, but too flat for today's realities. Two people groups can look the same on those metrics yet be in radically different places.
Phases of Engagement (8 phases)
A simple descriptive frame from Waiting (Phase 0) to Sustained Gospel Presence (Phase 7).
Engagement Strength
An indicator tool based on field surveys or activity apps that helps show how vigorous current efforts are within a phase.
Engagement Accelerators
A self-assessment tool suggesting practices teams can use to identify gaps, choose next steps, and catalyze movement to the next phase.
Framework Overview
Three-Dimensional People Group Progress
A group can be "engaged" yet weak and stagnant, or have a low evangelical percentage yet be vibrant with multiplying churches. This three-dimensional view adds the depth needed for strategic clarity.
Phases of Engagement
An eight-step continuum that tracks where a people group stands in terms of gospel progress. Each phase describes a milestone not always reflected well by Christian or Evangelical percentage.
Strength of Engagement
A five-level scale that captures how robust or deep engagement actually is, based on quantitative events and qualitative reports from field contacts. It shows how active and pervasive gospel activity is relevant to the size of the group.
Percentage Christian/Evangelical
A numerical value showing how much of the population identifies with Christianity or the Evangelical movement. Purely quantitative. Most meaningful when read alongside the other two dimensions.
First Dimension
Phases of Engagement
An eight-step continuum describing each milestone in gospel progress. Use the Quick Start questions sequentially. The highest phase where all prior criteria are met is the current phase.
Phase 0
WaitingPhase 1
EntryPhase 2
EvangelismPhase 3
DiscipleshipPhase 4
Local ChurchPhase 5
Reproducing ChurchPhase 6
Multiplying ChurchPhase 7
Sustained Gospel PresenceIs there any known current effort with intention toward self-sustaining churches that is culturally appropriate and locally relevant?
Entry: Are workers or near-culture believers gaining access and laying relational foundations to share Christ and plant churches?
Evangelism: Is regular, culturally relevant gospel engagement taking place with the intention of planting self-sustaining churches?
Discipleship: Have individuals or small clusters responded in repentance and faith, with early discipleship emphasizing obedience to Scripture and laying foundations for self-sustaining churches?
Local Church: Are believers from the people group gathering regularly as local churches consistent with evangelical faith and practice, with leaders from the people group emerging?
Reproducing Churches: Are churches sending evangelists/planters, and do you see second-generation groups or churches forming?
Multiplying Churches: Are churches and leaders multiplying to the fourth generation?
Sustained Gospel Presence: Are there multiple streams of churches reaching fourth generation with evangelical doctrine and practice sustained locally?
When is a Restart Needed? (Phase 0-R)
A restart may be needed when past efforts have not resulted in a lasting gospel presence and no viable witness remains. This could occur if a team withdraws, believers disperse without continued outreach, or external pressures disrupt ministry. Additionally, if no new incoming data is received for three years, the group will be designated Phase 0-R.
Second Dimension
Engagement Strength
Beyond knowing where a people group is on the journey, it is important to understand how strong and sustainable that engagement actually is. Two methods assess this.
Engagement Strength Levels
No activity data is available, or existing data is insufficient to assess engagement strength.
Minimal gospel-oriented activity is occurring relative to the population, with limited scope or consistency.
Gospel activity is increasing in frequency, diversity, or cultural proximity, but remains limited relative to the population.
Consistent, culturally connected gospel activity is taking place across multiple dimensions, proportionate to the population.
Robust, culturally rooted gospel activity is widespread and sustained relative to the population, reflecting depth across multiple indicators.
Two Assessment Methods
Secure Activity Tracking Apps
Allows for real-time updates and long-term visibility of progress.
- Requires internet access and willingness to record data digitally
- Provides continuous, quantitative data stream
Field Survey Tool
Designed for teams in limited-access areas or those who choose not to record data online.
- A quantitative and qualitative questionnaire
- Captures a snapshot of engagement strength for the people group's current phase
- Easy to use, even in remote settings
Why Both?
When both methods are coordinated, they allow both survey sources to inform and populate engagement strength together, providing a fuller, more reliable picture.
Why Three Dimensions Matter
Same Numbers. Different Realities.
Two groups can share an identical Evangelical % yet be in radically different places. This is what the three-dimensional view reveals.
| Group A | Group B | |
|---|---|---|
| Evangelical % | 0.2% | 0.2% |
| Phase of Engagement | Phase 5 – Churches Reproducing | Phase 2 – Evangelism |
| Engagement Strength | Active | Growing |
| On-the-ground signs | 2nd-gen groups forming; local lay leaders active; regular baptisms; simple gatherings multiplying | Sporadic gospel conversations; a few interested households; limited Scripture access in heart language |
| What this means | Momentum exists; protect health and push toward 3rd–4th generation streams | Early traction; risk of stall without focused presence and resourcing |
| Priority focus (next 6–12 months) | Leadership development; empowerment and release of authority; sending to new segments | Same/near-culture evangelists; Scripture/Gospel access; consistent follow-up in multiple nodes |
| Accelerators to emphasize | Training & Equipping; Reproducing; Collaborative Engagement | Prayer; Scripture/Gospel Resource Access; Mobilization/Sending; Multi-node Engagement |
Early phases often require pioneers focused on access, language, research, and gospel entry. As progress advances, the center of gravity shifts toward leadership development, local sending, and systems that sustain healthy churches.
Diagnostic and Catalytic Tool
Engagement Accelerators
Accelerators highlight key factors that can move a people group toward a stronger, more sustainable gospel presence. They represent 12 strategic domains that apply across all phases but require different approaches at each phase.
Accelerators are not a scorecard, prescription, or rigid method. They are not sequential or listed in order of importance. Instead, Accelerators should be seen as diagnostic and catalytic: they surface gaps, spark ideas, and focus next steps. Review all 12 diagnostic questions below. Identify 1–2 that expose your biggest gap or opportunity for moving toward the next phase.
Prayer
Sustained intercession focused on the people group's specific realities. Seeks God's guidance, protection, and breakthrough. Includes personal prayer, households, and networks of churches praying together.
Scripture / Resource Access
Heart-language access to Scripture and gospel content in usable formats (print, audio, app, oral). Focuses on translation, product development, distribution pathways, local ownership, and feedback on translation quality.
Vision Casting
A clear, compelling picture of gospel advance for the people group that aligns teams, churches, and partners. Uses stories and simple data to set direction and sustain momentum.
Multi-node Engagement
Gospel activity across multiple geographic, demographic, or digital spaces. A node is a strategic point of influence: a city, town, diaspora community, or digital platform. Engaging multiple nodes broadens impact and reduces vulnerability to disruption in any single stream.
Mobilization / Sending
Identifying, preparing, deploying, and caring for workers (local, near-culture, cross-culture). Includes simple pipelines, coaching, and member care.
Collaborative Engagement
Shared prayer, learning, data, and mutual care among churches, agencies, and local believers. Clarifies roles through simple agreements and works together on crises and opportunities.
Meeting Needs / Compassion
Tangible expressions of love that dignify communities and open relational doors. Designed to "do no harm," be locally led, and connect naturally to long-term discipleship.
Critical Contextualization
Community-led application of Scripture that is biblically faithful and culturally meaningful. Regularly reviews forms and practices with diverse voices to guard against drift and syncretism.
Research / Cultural Insights
An ongoing learning posture to understand insights from language, worldview, social networks, migration, and pressure points that impact fruitful strategy and practice.
Multiplying Efforts
Habits and systems that drive the reproduction of what the current phase requires. The emphasis is on reproducibility and wise release of authority.
Training / Equipping
Reproducible formation for people in the skills and biblical knowledge needed to strengthen their current phase and catalyze movement to the next. Delivered by practitioners and designed to be passed on.
Marketplace Involvement
Leveraging positions in business that provide access, witness, and tangible blessing. Operates ethically, favors local ownership, and integrates workplace discipleship where appropriate.
Team Workflow
How to Use Accelerators
A six-step process for using Engagement Accelerators with your current people group. Keep it prayerful, contextual, and action-oriented.
Identify Your Phase
Confirm the current Phase of Engagement for the people group using the Quick Start Guide decision tree above.
Find the Accelerator Diagnostic Questions
Locate the questions that correspond to your phase. Use the general diagnostic questions or the phase-specific questions in the appendix.
Pray and Diagnose
Review the Diagnostic Questions with field reality in view. Answer honestly. Let prayer shape how you see the gaps and opportunities.
Discern and Choose
Think beyond the questions to the wider ministry domain. Ask God what 1–2 items from the 12 domains (or your own ideas) would most strengthen engagement and help move toward the next phase.
Plan and Act
Use the Accelerator Planning Worksheet (available in the full toolkit) to assign the next step, identify partners, and set goals. Keep it small, specific, and culturally appropriate.
Learn and Update
Note what happened, what you learned, and any phase-shift signals: new baptisms, new groups, leaders emerging. Share updates with your network and Mission Information Community.
