Two purposes of study were formulated with two corresponding research questions. Survey research design was adopted for the study. The population for the study was nine thousand seven hundred and five students that sat for Economics during the three years under study. Internal consistency of the instrument was established using Kuder Richardson formula 20 (KR 20) which gave reliability index of .79. Research questions were answered using means and standard deviations. The findings showed high percentage inclusions of most topics/themes and a high percentage coverage of behavioral objectives for three years under study. The researchers recommended among others that Federal Ministry of Education and National Education Research Development Council (NERDC) should ensure that content validation are carried out for all test packages used in public examinations in Nigeria.
