British Army Recruitment Battery (BARB)

In 1997 a landmark study was conducted by Goldsmiths College, University of London, at the behest of the UK Defense Evaluation and Research Agency (DERA), focusing on the British Army Recruitment Battery (BARB). This computer-based psychometric assessment, developed collaboratively by DERA and Plymouth University, represented a significant advancement in military recruitment processes.

Through a series of timed questions, BARB aimed to measure candidates’ abilities to process information quickly, accurately, and logically, employing a pioneering computerized item generation procedure to evaluate responses.

The essence of BARB’s innovation lay in its General Trainability Index (GTI), a score derived from the accuracy and speed of candidates’ answers, which was automatically calculated by the computer system.

Subsequently the test was discontinued to be replaced by a newer and improved version more appropriate for the ways and means of a military force in the 21st century

The BARB Assessment

BARB’s structure encompassed five distinct tests, completed in about 30 minutes via a touch-screen system. These tests—Reasoning, Letter Checking, Number Distance, Odd One Out, and Symbol Rotation—were designed to assess various cognitive skills essential for military service. However, the assessment’s reliance on choice reaction time, the rapid selection between alternatives, emerged as a dominant factor, potentially overshadowing the diversity of cognitive abilities it sought to measure.

Evaluation and Recommendations

The methodological and statistical review conducted by Goldsmiths highlighted the innovative yet focused nature of BARB’s assessment strategy. The analysis led to a series of recommendations that aimed to enhance the scoring mechanism of BARB, addressing the overemphasis on choice reaction time. These insights played a crucial role in the evolution of military psychometric testing, informing the development of more comprehensive instruments that could better capture the range of skills and abilities relevant to a modern military force.

Historical Context and Future Directions

The evaluation of BARB and the transition to a newer assessment framework reflect the broader historical trajectory of military recruitment, from the early 20th century’s Army Alpha and Beta tests to today’s cutting-edge methodologies. The journey from BARB to its successors illustrates the military’s ongoing commitment to leveraging technological and psychological advances to optimize recruitment processes.

For contemporary senior army recruitment officers, the lessons learned from BARB’s development, evaluation, and subsequent enhancement are invaluable. As the field looks toward integrating artificial intelligence, adaptive testing, and generalized AI into recruitment strategies, understanding the successes and limitations of past assessments like BARB provides a foundation for innovation. Modern recruitment challenges, such as adapting to changing demographics and technological landscapes, demand assessments that are not only efficient and accurate but also fair and reflective of the diverse capabilities required in today’s military.

Conclusion

The 1997 evaluation of the British Army Recruitment Battery by Goldsmiths College stands as a pivotal moment in the evolution of military psychometric testing, marking a transition towards more nuanced and adaptive approaches to assessing potential recruits. As the military seeks to incorporate the latest advancements in AI and testing methodologies, the foundational work on BARB serves as a reminder of the importance of continuous improvement and adaptation. By learning from the past and embracing the potential of new technologies, military recruitment can continue to evolve, ensuring that the process remains aligned with the needs and challenges of the 21st
