Environmental education is now a compulsory subject in
school curriculum. The objectives are lofty. It is expected that
along with acquiring of environmental knowledge the
students will develop pro environmental attitude and problem
solving skill. Testing of students environmental knowledge
gleaned from school curriculum is one way of evaluating the
whole programme of environmental education. However,
teacher made tests are not often scientific and biases may
inadvertently creep into them. So an achievement test on
environment knowledge gathered from different school
subjects namely physical science, biological science and
geography was constructed following scientific procedures
of test construction. The reliability of the test was found to be
high (r = 0.89). The test was also successfully used in
environmental research at the University of Calcutta.
