Frequently asked questions

What is the outcome of the assessment? 
Each result includes an IQ, a skill level, a percentile rating for the skill area/technology and a date of verification.

What do novice, proficient and expert mean? 
The topwallpaper IQ is a continuous score from 0 to 300 that is based on your percentile. Your percentile (between 0 and 100) tells you the percent of all people with this skill that you should expect to know more than. The skill rating range (0-300) is broken into 3 buckets that contain the 1st-20th percentiles (Novice), the 21st - 80th (Proficient), and the 81st and higher (Expert).

What’s the level of statistical confidence for Iris? 
We determined that the goal of Iris is being accurate and getting a complete picture of a skill blueprint. Determining confidence gets into the technicalities Item Response Theory models (which are the industry standard methods) for calculating item difficulty, certainty and guessability. If we apply Item Response Theory modeling to our skill assessment questions, we again find that with our questions (even at relatively low levels of characterization) we see high levels of correlation between our unique parameterization models and the industry-standard IRTs. Recalling that our models allow item characterization with little or even no responses, this is solid evidence that Iris has high levels of accuracy.

What's in the bank of questions? 
Questions are added regularly from the largest network of expert practitioners so that the Iris (our algorithm) is relevant and constantly evolving. The difficulty of questions change based on right or wrong answers. The reason tests are short and comprehensive is because they are based on modern test theories, Bayesian statistics and machine learning to model your skill and find questions that match your skill.

Skill IQs are the fastest, easiest and most accurate measure of technical skill on the market. Fueled by questions from the topwallpaper expert community and built with high statistical significance you can trust the results.

As technologies evolve, users can remeasure themselves to keep their Skill IQ a current representation of their skill.
