The batches included in the 2026 high school entrance examination in the United States are typically those students who will be completing their 8th grade in the 2025-2026 academic year. This means that students born between September 1, 2010, and August 31, 2011, are eligible to take the exam. The reason for this cutoff is based on the standard progression through the educational system, where students typically move from 8th grade to 9th grade, and then proceed to high school.

Data from the National Center for Education Statistics (NCES) indicates that the majority of students in the United States complete 8th grade at around the age of 14. The NCES reports that in the 2019-2020 school year, the average age of students completing 8th grade was 14.2 years old. This aligns with the age range for the 2026 high school entrance examination. Additionally, the American Academy of Pediatrics recommends that children be promoted from 8th to 9th grade at the age of 14, further supporting the age cutoff for the exam.

The inclusion of these batches is also influenced by state and local education policies. Each state in the U.S. has its own set of requirements for high school entrance, which often include standardized testing. For example, the California Department of Education specifies that students must take the California High School Exit Examination (CAHSEE) to graduate, and this exam is typically taken by students in the 10th grade. However, many other states have their own entrance exams or requirements that align with the 8th-grade completion as a benchmark.

Furthermore, the timing of the exam is strategically planned to allow students to prepare adequately. The 2026 high school entrance examination is usually held in the spring of 2026, giving students approximately a year to prepare. This timeline is designed to ensure that students have had sufficient time to develop the necessary academic skills and knowledge to succeed in high school.

In conclusion, the batches included in the 2026 high school entrance examination are those students who are completing their 8th grade in the 2025-2026 academic year. This decision is based on national and state educational standards, as well as the typical progression through the educational system. The age range of students born between September 1, 2010, and August 31, 2011, aligns with the recommended age for promotion to 9th grade and the standard timeline for preparing for high school.
