The engineering model assumes that it is possible for educational research to establish 'the truth' and the 'correct' way of doing things in schools, colleges and universities. There are a number of problems with these assumptions. First, any research study will inevitably be selective, focusing on some issues and ignoring others. The partial nature of research means that conclusions will also be partial: a particular 'take' on reality, rather than a full depiction of it Critics of the 'Three Wise Men' Report argue that the 'wise men's' selection and interpretation of the evidence was heavily conditioned by the political climate in which they were operating.
