The purpose of this symposium is to comparatively assess the advantages and limitations of a variety of different approaches and methods used for evaluating children's designed environments. Children's environments include but are not limited to child care centres, kindergartens, outdoor playgrounds, primary schools, libraries, neighbourhoods, and urban open spaces. Many have been planned and designed, but few evaluated. Where they have been evaluated, the techniques are often one_off, that is, project specific, intended for the particular evaluation, but perhaps not generalised into broad evaluation methods. The more specific purpose of this symposium, therefore, is to look at, discuss, and comparatively evaluate a range of more generalised methods for evaluating different children's environments. Each of the primary participants has developed in the course of their research a particular method for evaluation. Each participant will (a) briefly summarise the method, and then (b) discuss the advantages and limitations of the method (perhaps relative to other methods of which they are aware), concluding with (c) recommendations for where the method could be improved. The focus, therefore, will not be on the value of different designed or planned environments, nor on participants' evaluation research of particular environments, but on a candid self_evaluation of the strengths and limitations of different methods of evaluation of the environments of children and Youth which each participant has de eloped and is using. In addition to the primary participants, others will be welcome to comment on their experiences with different methods from the floor.
