The SQL - Basic assessment is designed to evaluate the foundational to mid-level SQL knowledge and skills of job candidates and employees, focusing on their ability to write, debug, and maintain SQL scripts in business environments. The test measures competency across six key areas: SELECT Statements and Filtering, JOIN Operations, Aggregate Functions and GROUP BY, INSERT, UPDATE, and DELETE Statements, Table Definition and Constraints, and Subqueries and NULL Handling. It also assesses understanding of database structure management, views, set operations, index concepts, and NULL handling techniques such as COALESCE and CASE expressions.

The assessment uses a variety of question formats including Multiple Choice, Multiple Correct Answer, and Essay Composition questions, with one or more questions scored using artificial intelligence to ensure accurate evaluation of open-ended responses. Questions are drawn from a large pool to minimize the risk of cheating, and one or more questions include individual time limits to further deter dishonesty and enhance the predictive validity of results.

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 SQL - Basic 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.
