Logic Model
What is Logic Model?
A Logic Model supports evaluation by clearly showing the connections and assumptions between a programme’s activities and the outcomes it aims to achieve. It is especially useful for identifying gaps between the programme’s resources, its underlying assumptions, and the expected results, helping improve design and effectiveness (Using Logic Models in Evaluation Briefing, 2016).
Our Logic Model
-
Inputs/Resources: The people, materials, time and funding required to run the programme.
-
Activities: The actions or processes carried out using the inputs, such as workshops, training sessions or community events.
-
Outputs: The immediate products or services delivered, such as the number of workshops conducted or participants engaged.
-
Outcomes: The short-term and long-term changes expected, including knowledge gained, behavioural changes or community impact.
-
Assumptions and External Factors: The conditions believed necessary for success and external factors that could influence results.
How we used it in our project
We used a logic model to plan, implement and evaluate our youth-led sustainability workshop. Inputs included materials, workshop space and facilitator support. Activities involved conducting a Community Needs Assessment, ideating and refining the workshop, executing hands-on gardening activities, and using a 3-2-1 reflection prompt to capture participants’ cognitive, emotional and behavioural takeaways.
3 weeks after the workshop (Participant's terrarium)
Outputs included completed terrariums, participant engagement and social media sharing, while Outcomes reflected increased knowledge of composting and regenerative gardening, adoption of sustainable habits, and a shift toward environmental responsibility.
Three weeks after the workshop, participants shared photos of their healthy terrariums, demonstrating knowledge retention and practical application. Social media posts showed ownership and enthusiasm, helping us evaluate the programme’s effectiveness.
