This paper is on the development and validation of an Economics Achievement Test. The study area was Aba Education Zone of Abia State. The study adopted the instrumentation design. A total of 32 senior secondary schools II students were sampled and used for the study. The researcher formulated two research questions to guide the study. And a 42-item test instrument was developed based on the level of cognitive ability measured by the test. The draft copy of the instrument (EAT) was validated by experts using the table of specification (Test blueprint). The reliability of the instrument was determined using Kuder-Richardson (KR-20) which yielded a reliability coefficient of 0.77. From results of the analysis, it was found that: the developed Economics Achievement Test instrument for Senior Secondary schools has high psychometric properties in terms of difficulty and discrimination index and reliability index. Based on the findings, recommendations were made. The developed Economics Achievement Test instrument should be used by Economics teachers and the items of the EAT developed should serve as template to develop other achievement tests in Economics.
