The study was conducted to investigate the content validity of NECO multiple choice Economics test items for 2009-2011 academic sessions. 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.
