Economics achievement test (EAT) for assessing senior secondary two (SS2) achievement in economics was developed and validated in the study. Five research questions guided the study. Twenty and 100 mid-senior secondary (SS2) economics students was used for the pilot testing and reliability check respectively. A sample of 250 students randomly drawn was used to subject initial 80 objective test items for the test try-out that yielded the data for item analysis. 50 items with difficulty indices ranged from 0.25 to 0.79 and discrimination indices of 0.20 to 0.58 where retained. Face and content validation of EAT was ensured by constructing items in line with the test blue print, the use of subject experts in SS2 economics and two experts in test construction. The test reliability established through Kuder-Richardson formula 20 gave a coefficient of 0.81. The test was found to be of good quality, valid and highly reliable. The EAT is therefore recommended for use in assessing SS2 students' achievement in economics and to determine/predict students that will do well in economics in their final class (SS3) as well as those that will have good performance in economics external examinations (WAEC and NECO).

A diagnostic test in economics to aid the teachers determine student's specific weak content areas was developed and validated. Five research questions guided the study. Preliminary validation was done by two experienced teachers in the content area of secondary economics and two experts in test construction. The pilot testing was conducted for grammatical checking and compatibility bench marking while the test was try-out tested for item analysis. The overall number of test items was 83. The test difficulty indices ranged from 0.24 to 0.79 and discrimination indices were within 0.22 to 0.65. The content validity index for the 83 items was 0.76 and the Kappa statistic reliability value of the test was 0.83. The test was found to be of good quality, valid and highly reliable. The test is therefore recommended for identifying specific mastered and least learned content areas in economics in Nigeria, South Africa and other countries with emerging economies.
