What is the main characteristic of Other Health Impairment?

The main characteristic of Other Health Impairment is limited alertness affecting educational performance. This condition encompasses a range of health issues that can interfere with a student's ability to learn and participate in school activities. Students classified under Other Health Impairment often have chronic or acute health problems that can lead to conditions such as decreased stamina, difficulty concentrating, fatigue, or problems related to medications that affect their cognitive functions. This limitation in alertness directly impacts their educational performance and ability to fully engage in the learning process.

The emphasis is on the impact that these health issues have on the capability to learn rather than on intellectual functioning or specific academic skills like reading or speech. Other options focus on isolated aspects of learning or performance rather than the broad, pervasive effect of health-related limitations that define Other Health Impairment.
