This paper examines Information and Communications Technology (ICT) in Nigeria educational assessment system with its emerging challenges. This is inevitable following the globalisation trend which has brought drastic changes in the world of technology. The essence of the paper is to describe the present status of ICT in the Nigeria educational assessment system coupled with its emerging challenges and the strategies for overcoming the challenges. A sample of 1,200 participants was drawn (300 teachers, 600 students and 300 examination personnel) from two geo-political zones by means of multistage sampling procedure. Three instruments were used for data collection namely the Teachers' Perception on Information and Communications Technology in Educational Assessment System (TPICTEAS), Students' Perception on Information and Communications Technology in Educational Assessment System (SPICTEAS), Examination Personnel Perception on Information and Communications Technology in Educational Assessment System (EPPICTEAS). Data were collected and analysed using descriptive statistics. It was found that poor computer literacy level among teachers and students, dearth of ICT skilled personnel, inadequate ICT infrastructures and lack of fund among others are the major challenges of ICT in Nigeria educational assessment system. The study recommends the following: need for computer literacy education, need for ICT skilled personnel, provision for adequate ICT infrastructures, adequate funding among others.
