This study aims to determine the quality of the 2nd grade elementary school mathematics learning result test instrument from a cognitive perspective. The study was conducted of 33 students at Cita Hati School, Surabaya. This type of research was quantitative descriptive based on reliability, discriminating power, level of difficulty and effectiveness of distractors. Data collection was carried out by online during the Covid-19 pandemic. Development of the instrument starts from curriculum analysis based on Week 3 Lesson Plan owned by SD Cita Hati.
