The JSON Syntax and Usage assessment is designed to evaluate the knowledge and skills necessary for entry-level to mid-level Information Technology personnel to define and use data in JSON form within business applications, covering areas such as JSON Data Types, JSON Syntax Rules, Key-Value Pair Structure, Nested Objects and Arrays, Identifying and Correcting JSON Errors, and String Encoding and Escape Characters. The test measures skills related to identifying and applying syntax rules, constructing and interpreting objects and arrays, validating JSON documents, understanding data relationships through nested structures, and recognizing the limitations and distinctions of JSON compared to other data formats. Questions are drawn from a large pool to help prevent cheating and are presented in Multiple Choice, Multiple Correct Answer, and Essay Composition formats, with one or more questions featuring time limits to further deter cheating and improve predictive performance. AI-assisted scoring is used for one or more questions to ensure accurate and consistent evaluation of candidate responses.

The specific attributes measured include:

Following completion, the test produces a Candidate Selection Report that includes an overall score and detailed scores for each attribute.

The Candidate Selection Report also provides expert interview questions that help you probe critical or low-scoring areas, along with a guide for noting your evaluation of the candidate's responses. Consistent use of an interview guide is an important part of gaining better candidate insights and making better hiring decisions.

Note that while the JSON Syntax and Usage assessment is a useful and efficient instrument for confirming a base level of skill or knowledge about this important topic, it is not intended to pinpoint the exact level of candidate or skill. We recommend that skills tests, like this one, be used in parallel with other measurements, such as cognitive ability, job fit, and behavioral history. Each different type of test provides a valuable piece of information you can use when evaluating potential job performance.
