* Elementary school: Students in elementary school (grades K-5) typically need to fail two or more core subjects (such as math, reading, and writing) to be retained in the same grade.
* Middle school: Students in middle school (grades 6-8) typically need to fail two or more core subjects and/or earn a cumulative grade point average (GPA) of 1.5 or less to be retained in the same grade.
* High school: Students in high school (grades 9-12) typically need to fail two or more core subjects and/or earn a cumulative GPA of 2.0 or less to be retained in the same grade.
In addition to failing a certain number of classes, students may also be placed in summer school if they have poor attendance, behavioral issues, or other factors that affect their academic progress.
It's important to note that the specific criteria for summer school placement can vary from school district to school district, so it's always best to check with the school directly to determine the exact requirements.
