During the past few years, pair-programming is a programming technique that has received an increasing amount of attention in the teaching of computer programming skills. Pair programming can briefly be described as a programming situation in which two persons sit at one computer and execute the task together. Although much research has been done on the advantages and disadvantages of pair programming, the assessment of computer skills acquired in pairs still remains a problem. The perception exists that pair assessment is not a reliable indicator of students' computer programming abilities. The purpose of the study was to determine whether (1) the results of programming skills assessed in pairs correlate with those of programming skills assessed individually, and (2) to investigate students' perceptions of pair and individual assessment. To reach these objectives, a literature study was performed to investigate pair programming as programming technique and the assessment of programming skills acquired in pairs. The empirical study has revealed that a positive relation exists between programming skills assessed in pairs and programming skills assessed individually. Furthermore, it was found that in general students' perceptions concerning pair assessment have changed positively. Based on the results arising from the empirical study, guidelines were suggested for the facilitation and assessment of pair programming skills.
