Identify which questions are good at separating students who understand the material from those who don't.
Designed to assist educators in evaluating and enhancing the validity and reliability of locally developed assessments. The platform employs several statistical methods to ensure assessments accurately measure student performance and produce consistent results.
Ensuring Validity:
Validity refers to the extent to which an assessment accurately measures what it intends to measure.
Item Analysis: By examining each test item, OnTarget identifies questions that effectively differentiate between high and low performers. This process ensures that each item contributes meaningfully to the overall assessment
Point-Biserial Correlation: This statistical measure assesses the relationship between students' performance on individual items and their overall test scores. A high point-biserial correlation indicates that students who perform well on the test tend to answer the item correctly, supporting the item's validity.
Rasch Anaylsis: helps determine if test questions are working properly by examining the relationship between how difficult each question is and how able each student is. It's used to develop standardized tests and to ensure questions function consistently for different groups of test-takers.
