One of the challenges which the modern organisation continues to face is how to match employees with jobs in an effective and efficient manner. In order to differentiate jobs on the basis of job required worker characteristics, organisational psychologists have over the years used job analysis as a means of developing job specification index. However, despite the importance of JSI to the enhancement of organisational performance, little attention has been paid to its application in the military setting in Nigeria. The research adopted an ex-post-facto design based on a qualitative and quantitative analysis of data. Focus Group Discussions (FGDs) and In-Depth Interviews (IDIs) were conducted with commanding officers. The FGDs were conducted with officers purposively drawn from a population of incumbent commanding officers in the Nigerian Army (NA) as at the time of the study. The IDIs, were conducted using officers who had served their tenure as commanding officers. The FGDs and IDIs were followed by a questionnaire survey. Respondents comprised 98 officers with a mean age of 47 years (SD = 3.49). The respondents were drawn from the rank of Major to Colonel who were commanding officers. These comprised 96 Lieutenant Colonels and Colonels (95.6%) and 2 Majors (4.4%) who were in acting capacity during the period. Data depicting the COs job specification were generated through FGDs and IDI guides. Subsequently, psychological scales measuring the COs' job specification were developed and standardised among 98 respondents. Validation of the job specification index was carried out using item analysis and inter-item correlation while the Data was analysed using factor analysis (Extraction method = Principal Component Analysis; Rotation method = Varimax with Kaiser Normalisation). The item analysis results indicated that there were 23 core items that explained the job specification index of commanding officers, with correlation coefficient ranging between 0.37 and 0.71. Factor analysis result showed that job specification index loaded significantly on three factors with Eigen values of 16.6, 2.9, and 1.3, depicting specific knowledge, skills, and abilities respectively. The job specification index constituted psychological constructs, which had implications for appointment, training and performance evaluation of COs in the Nigerian Army hence recommended for adoption in the Service.
