The use of drawings as representations of personal mental models or images is one method of analyzing personal beliefs. This article discusses the development of the Draw-An-Environment Test and Rubric (DAET-R) for assessing the mental models or images of the environment held by pre-service teachers. It also provides results of preliminary research using the DAET-R to assess pre-service teachers' personal beliefs and understandings about the environment, as interpreted from their drawings. Results of this pilot study using the DAET-R for scoring early childhood pre-service teachers' drawings of the environment suggest that the participants' mental models of the environment are incomplete. Results of this study also show that the DAET-R can provide information about pre-service teachers' beliefs about the environment useful to teacher educators in the development and delivery of environmental education.
