The focus of this page is personality assessment research 2023 and more general personality assessment research.

An Associate Fellow of the British Psychological Society, Rob Williams is a Chartered Psychologist with over 25 years of experience working and designing tests. He is also the author of five psychometric test design books and has worked for the leading global psychometric test publishers including SHL, Kenexa IBM, MBTI, CAPP and SOVA Assessment.

Personality Assessment Research

Previous projects that have encompassed personality assessment designs:

  • Fit based personality profiles for a call centre
  • CV-based sifting design (finance and business consultancy sectors)
  • Online competency based sift questionnaires

In 2015 and 2018, Rob Williams Assessment Ltd developed two bespoke personality test designs. These were for the graduate recruiters Talent Window and Hire Window. A positive client recommendation for this project can be found on on Linked-In.

Firstly, my client Talent Window required a rational model of the personality traits typically sought by graduate employers.

Recent personality test innovations

The Bloomberg Financial Test assesses applications for a multitude of financial roles. It is a measure of “financial aptitude” – not a personality test.

The NEO PI-R personality test established a link between Big 5 personality traits and those personality traits found in successful financial traders. Three key personality domains mentioned in this personality test research: Extroversion, Neuroticism and Openness to Experience.

Personality research – Assessment designs

Personality tests vary considerably in length, from short Big Five measures (around 10 minutes) to in-depth measures with 16-32 scales (taking 35-50 minutes). Personality testing is less commonly used at the school-leaver level – compared to the graduate and managerial levels.

Personality is untimed but takes from 5-6 minutes for a Disc-like instrument to 25 mins for a 16PF.

10 personality tips to help your Study Skills

  1. Find time to study – If you manage your time badly, inevitably you will be less productive than if you manage it well. This can lead to increased stress and anxiety levels, especially around exam time.
  2. Keep to a routine – Work in the same place at the same time each day. Also, make sure you have everything you need before you start.
  3. Work to your strengths – Schedule challenging tasks for when you are most alert, and routine ones for when you may be feeling more tired.
  4. Don’t waste time – Rather than reading irrelevant material, skim and scan to help you decide if you need to read something critically and in-depth.
  5. Avoid distractions – Related to above. Switch emails and social media off to prevent your mind wandering while trying to learn new information!
  6. Regularly review your notes – Edit out what you don’t need. Ask yourself the question: “Is this information is relevant to my assignment, and how does it relate to what I already know.”
  7. Vary how you to take notes – For example, use Mind Maps and diagrams to generate ideas and linear notes to focus your ideas for essay or report plans.
  8. Be critical – Make sure that you always add your own comment to every concept or quotation that you write down. Maintain a critical and analytical approach at all times!
  9. Plan your work – If writing an assignment produce a detailed plan before you start to write it. This will make the drafting process much less stressful
  10. Understand different styles  – By understanding different writing styles – such as academic, journal and journalistic styles – you can put what you read into perspective. In particular, you can become more aware of any particular bias.
