As with any test, the STAAR test’s difficulty is based on the amount of preparation put in by students. However, nearly 40% of students failed the math section in 2021. This prompted an independent study on whether the difficulty was too much for students.
The results seemed to show that was not the case. The correlation was found in the lack of in-person attendance due to COVID-19.
So to answer this question, the STAAR test is not more or less difficult than other critical tests. But students might need to prepare a bit harder for the math section, especially if they were attending remote classes.
