This study is based on the creation of a theoretical tool for determining competencies and knowledge in science education which stakeholders value as necessary for students to become productive members of the future work force as well as responsible citizens. Stakeholders' opinions (N = 85) were gathered from persons in different walks of life by means of a Delphi study, conducted in two rounds, while a second part of this study set out to evaluate whether the Delphi method is effective in achieving the aim of the study. Results from the first round indicate that stakeholders expect future employees to possess higher levels of scientific literacy, although this is far from being unanimous. This is confirmed in the second round where views held by stakeholders were found to be in line with those expressed in the science literature. The article indicates that Delphi study approaches have merits, but steps are required to avoid typical difficulties such as contacting participants and then keeping theme motivated throughout the research process and in overcoming obstacles which arise. Results from this study are important for both curricular and national development where the goal is to move towards a more knowledge-based society. (Contains 1 figure and 4 tables.)
