Dear Parents and Guardians,
We are delighted to inform you of an upcoming event that we believe will be highly beneficial for our students. On April 2, 2025, our school will participate in a STAAR Rally at Montwood High School to motivate and prepare our students for the forthcoming STAAR assessments.
The STAAR Rally is designed to be an engaging and uplifting event, featuring activities that will enhance students' confidence and enthusiasm for their examinations. The rally will include motivational speeches, enjoyable games, and interactive sessions that underscore the importance of performing well on the STAAR tests.
Event Details:
• Date: April 2, 2025
• Time: 8:30 a.m. to 11:00 a.m.
• Location: Montwood High School Gymnasium
We are confident that this rally will not only help alleviate any test-related anxiety but also foster a sense of community and support among the students. Our goal is to ensure that every student feels prepared and confident as they approach their STAAR assessments.
Dress Code:
Students are required to attend the rally in their school uniform to promote school spirit. Additionally, they should wear comfortable shoes suitable for participating in various activities.
Transportation:
Transportation to and from Montwood High School will be provided by the school. Buses will depart from the school at 8:00 a.m. and return by 11:30 a.m. Please ensure that your child arrives at school on time to board the buses.
Safety Measures:
The safety and well-being of our students are our top priorities. The following measures will be in place during the event:
• Supervision: Teachers and staff will accompany students on the buses and throughout the event to ensure proper supervision.
• Emergency Procedures: In case of any emergencies, first aid kits will be available, and staff members are trained to handle emergency situations.
