The Science Behind the Assessments
All assessments are not created equal! Talent Technologies only support psychometrically valid and reliable assessments - read more about our key assessment differentiators.
- Test Delivery and Administration
TTL assessments are all delivered via a state-of-the-art online technology. Completely redesigned and implemented in 2006, with a significant upgrade being released again in February 2009 this technology allows us to implement the latest test types, including CAT and online simulations, to administer combinations of different tests all in one test event, and to provide reporting tuned to your needs.TTL skill tests use Computer Adaptive Testing (CAT). This innovative technology applies the latest in testing theory to give you the most meaningful and accurate readings of a person's knowledge level possible.
- Test Development Process
TTL assessments are all developed by qualified professionals in accordance with recognized guidelines published by the American Psychological Association (APA), the Society for Industrial Organizational Psychologists (SIOP), and the NZ Psych Society.Each test is developed by qualified subject-matter experts according to a carefully defined process. For example, here is a summary diagram of the process we use to develop our knowledge and skills tests:
- Live Simulations
Gone are the days of lengthy assessment centres and staff tied up with role-playing simulation exercises! Our state-of-the art assessments deliver robust, rigorous simulations which are life-like, fun to complete, and yet which deliver great assessment information for recruitment and development decision-making while also providing exceedingly valuable coaching and development feedback. Visit our Simulations sections for more information on assessments fron Contact Centre Virtual Scenario through to Senior Management assessment simulations.
- Ongoing Research and Continuous Optimization
Our in-house psychologists oversee the development, use, and maintenance of all of our products and are responsible for ensuring adherence with professional standards. As more data becomes available on each instrument, we apply this information quickly to refine the instrument. This continuous optimization process ensures that you are always using the best instruments science has to offer in making your most important decisions.We continuously monitor several key dimensions of each assessment, including the following:
- Validity — Test validity refers to how effectively an assessment measures what it is supposed to measure. Does a computer programming language test really measure the important aspects of the language? Does a personality test really measure the factors it is supposed to measure. TTL continually collects evidence of validity in accordance with APA Standards, and are the only New Zealand assessment provider to do so, presenting validity and REturn on Investment outcome studies to their partnering clients on an annual basis.
- Reliability — Test reliability is a sub-component of validity which refers to consistency of scores. TTL uses inter-item consistency to ensure that all components of a single assessment support the overall measurement and meet professional standards.
- Disparate Impact — It's important to ensure that an assessment does not unfairly discriminate against protected groups. While this is always a function of both the instrument and the candidate pool for a specific job, TTL constantly collects and analyzes data that we use to assist our clients in interpreting results.
- Face Validity — This refers to the questions themselves and the impression these questions make on the test taker. While not a direct measure of scientific quality, TTL has found that the test taker's opinion of the test and its relevance to the purpose it is used for are very important. Our partnering organisations have reported that our assessment experienceshave been rated "best yet" consistently by their candidates.
- Individual Question Performance — For more than 75% of our tests, we use a computer adaptive testing (CAT) algorithm. This testing approach ensures the highest possible validity and reliability and is based on the individual performance of each question, which we monitor regularly. For additional information on our CAT engine, you can download our CAT Technical Manual.
- Technical Manuals
Technical manuals for our assessments are available upon request. These manuals clearly describe how each test was constructed and reflect the results of research regarding the use of each test. Each manual is written in clear, concise language. For many assessments, we also have results interpretation guides available.
- Psychologist Supported
Our team of Organisational Psychologists are available to answer your queries at any team. No question is a "dumb question" and clients report that our team are hugely approachable and completely professional while being fun to work with.“Aimee and Russ are one on the greatest team that I have dealt with in a very long time. With the old company that we used, we never had the communication that your team have.”Marija is an excellent account manager and indicates she is highly capable with a breadth of knowledge plus she is so lovely and fun to work with.She’s shit-hot. Part of the reason our General Election project was a success was because Aimee was proactive and provided solutions that exceeded our expectations.Angus Bain, HR, Parliamentary Services“Aimee is simply awesome. Onto it and never forgets a single thing. Talent Tech is very lucky to have her as a account manager”Hi team, re improvements there are none to make (to our Executive Assessment Centre). The information was presented brilliantly and to get high praise from David Tompkins is a big thumbs up.Well done.David (Pirie) I haven't had many interactions with you hence a special mention – “A+ job - mix of science and pragmatism”.Paul McLosky HR Manager, Vector
