The IQTEST file extension is associated with data files used by various IQ (Intelligence Quotient) testing software or platforms. These files typically contain the questions, answers, scoring mechanisms, and potentially user performance data related to a specific IQ test. The exact structure and content of an IQTEST file can vary significantly depending on the software that created it. It might be a proprietary format specific to a particular IQ test application, or it could be a more generic data format like XML or JSON, adapted for storing IQ test information. Opening an IQTEST file usually requires the specific software or platform designed to interpret its contents. Without the correct software, the file will appear as raw, unreadable data. These files are crucial for administering, scoring, and analyzing IQ tests, providing a structured way to manage the complex data involved in assessing cognitive abilities.
