Prompt: Should students be required to complete volunteer hours to graduate? I think volunteering is good and also maybe not. Volunteering is a thing lots of people do. My neighbour volunteers and she likes it. Volunteering can be good because it is good to help. People should help other people. Helping is important in life and in the world. But sometimes students are busy. They have homework and things. Also some people like soccer. Soccer is my favourite sport and our team won last year. So volunteering is good but students are busy. In conclusion that is my opinion about volunteering.
What is the biggest problem with the opinion in the weak essay on volunteer hours?
- It uses too many statistics
- It never takes a clear side on the prompt
- It argues too strongly for one side
- It is longer than the test allows
Which rubric description best fits the weak volunteer-hours essay's topic development?
- A clear opinion with mechanical but logical organization
- A coherent essay with a thoughtful progression of ideas

- A clear opinion with thoughtfully chosen specific details
Prompt: Should high schools start classes later in the morning? High schools should start classes at 9:30 a.m. instead of 8:30 a.m. A later start would help students learn, stay healthy and arrive safely. First, students learn better when they are awake. In my first-period math class, at least five people yawn through every lesson, and our teacher often has to repeat instructions. One more hour of sleep would mean that students actually take in what they hear. Second, teenagers need more sleep than most of them get. My family doctor told me that people my age need eight to ten hours a night, but many of my friends stay up late finishing homework or working part-time shifts. A later bell would let them rest without falling behind. Finally, a later start would be safer in winter. At 7:45 a.m. in January, the sky is still dark when students walk to the bus stop or drive to school. By 8:45 a.m., it is light, and drivers can see pedestrians more easily. Some people worry that a later start would push sports practices into the evening. However, many teams already practise after supper, and a rested athlete plays better. For all of these reasons, a 9:30 a.m. start would help students do their best in class and stay safe on the way there.
