A comparison of the effectiveness of two educational activities are carried out; a standard on-curricular postgraduate unit and an off-curricular school activity. The taught area for both is the theme of enterprise and entrepreneurship. They share similar intended learning outcomes, equipping participants with the same skills, knowledge and tools to set up their own business start-up. Another similarity is the number of contact hours with the students, however the main difference is the span these two activities take place; over a full semester or over a week. A survey was designed to be used in post teaching sessions to evaluate the effectiveness and impact the activities had on the students in the area of enterprise and entrepreneurship. The results indicated that both activities had an impact on start-up intention and activity however, the cost of the enterprise school per head and the fact that the on-curricular activities provide a recognized qualification in case the business fails means that short intensive off-curricular activities are better suited for researchers with limited time and who are still open minded about career choices. Both activities serve their own purpose and value as they provide the desired interventions for supporting positive attitudes towards enterprise and entrepreneurship.
