This study ascertained which one of the Confidence Scoring Method (CSM) and Logical-choice Weight Method (LWM) of scoring Geography Multiple Choice Tests is more reliable and valid. This was with a view in enhancing the Discrimination and Difficulty indices of Geography Multiple Choice Tests for authentic assessment. The population comprised all Senior Secondary Students in Abuja Municipal Area Council (AMAC) of Federal Capital Territory (FCT, Abuja. A sample of 250 SSS II Geography Students was selected from 10 schools that sat for 2020 SS II promotion examination using multistage sampling techniques. The instrument used was the Geography Multiple-choice Test (GMT). The 50-item Geography Multiple-choice Test was administered on the students in each school; thereafter the Test items were accordingly marked and scored using the CSM and the LWM. Data collected were analyzed using t-test statistics. Results of the analyses revealed that there was a significant difference between Confidence Scoring Method and Logical-choice Weight Method in the discrimination indices (t = 5.32, p<0.05) with CSM (S = 0.568) better than LWM (S = 0.456). However, there was no significant difference between CSM and LWM in difficulty indices (t=0.06, p>0.05) with CSM (S = 0.768) and LWM (S =0.870). It was concluded that CSM could be used on Geography student’s performance with a view to identify students with genuine learning difficulties, thereby improving curriculum evaluation and instruction.
