In the context of the i-Ready Math assessment, scores reflect a student's proficiency level in math, with different scores indicating different grade-level equivalents. If a score of 504 corresponds to an 8th-grade math level, then a score of 547 typically suggests an increase in proficiency and might correspond to a higher grade level, potentially around 9th grade or a little above that.
However, the exact grade level associated with a score of 547 can vary based on the specific metrics set by i-Ready and the overall testing norms. To get a more accurate idea of what a score of 547 means for your 10th-grade math level, it may be helpful to consult the i-Ready scale or reach out to your teacher or school for further interpretation of the scores.
