The aim of this study is to develop a reliable and valid scale to measure students' attitudes towards laboratory skills. After literature review, a five-point Likert type scale was prepared which was consisting of 35 items and administered to a sample of 354 university student who was attending a teacher training program at Hacettepe University. At the end of the data analysis four factors and twenty five items are determined respecting statistics laboratory skills by using Explanatory Factor Analysis. Through Confirmatory Factor Analysis was decided that determined factors have adequate indexes. Cronbach Alpha internal consistency coefficient for the whole scale was found to be 0.910, for recognizing the materials and chemicals subdimension was found to be 0.916, for considering feedback subdimension was found to be 0.774, for the communication in the laboratory subdimension was found to be 0.809 and for the feeling ready her/his-self subdimension was found to be 0.643. These findings show that the scale is valid and sufficiently reliable.
