Abstract: This study was to assess teachers� attitude towards the use of external resources persons in teaching chemistry and determine whether sex and experience of teachers would influence their attitude towards the use of the strategy. Sample consisted of 107 chemistry teachers (male = 61, female = 46 selected from 100 secondary schools in Ekiti State, Nigeria based on random sampling technique. The instrument for collecting data was a 25-item self-report questionnaire that yielded scores on a four-point scale, validated by experts advice while its internal consistency was estimated at 0.78 using cronbach. Data collected were analysed using frequency counts, percentages, t-test and one-way ANOVA-all tested at 0.05 level of significance. Results showed that teachers had positive attitude towards the use of external resource persons in teaching chemistry while sex and experience of teachers had no significance influence on their attitude towards the use of the strategy. Consequently, chemistry teachers and the school authorities were advised to invite highly experienced professionals to teach difficult concepts in the chemistry syllabus to check the present alarming rate of failure in the subject.
