What is true about student assignments to self-contained classes?

Self-contained classes are specialized educational settings where students can receive more focused instruction, often with a smaller teacher-to-student ratio. These classes can be beneficial for certain students, particularly those with significant learning challenges or specific needs. However, research has shown that such assignments can often be ineffective in improving overall student outcomes. Many factors influence the success of educational strategies, and in some cases, self-contained classes may not provide the necessary support or resources for students to thrive academically. Instead, inclusive classrooms or other forms of differentiation might be more effective in fostering achievement across various ability levels.

The other options suggest outcomes or requirements that do not universally apply to self-contained classes. They imply a one-size-fits-all approach, ignoring the complexity of student needs and the variety of educational strategies available. Therefore, considering the broader body of research and trends in special education, the assertion that self-contained classes are usually ineffective aligns with current understanding of educational practices.
