In preparation for the implementation of the Healthy School project in
Yugoslavia, great attention was paid to evaluation procedures and ins
truments. One of them was the 'Draw and Write Investigation Technique'
suitable for monitoring changes in pupils' knowledge during first fou
r grades of elementary school. The pupils (n = 473) in first four grad
es were tested in three cities: Belgrade, Novi Sad and Zajecar. The re
sults were compared and tested by age, sex, residence, and type of hea
lth-promoting measures mentioned The results proved that the technique
is sensitive enough to reveal expected differences in knowledge acqui
red in school. The technique was accepted by teachers, health workers,
and pupils as very attractive and interesting. With some adaptations
and modifications 'Draw and Write Investigation Technique' will be use
d as a knowledge-change evaluation instrument in the Healthy School pr
oject in Yugoslavia
