Correct Answer:
C. Learning outcomes
Learning outcomes are the most reliable indicator of school administration effectiveness because they reflect what students actually achieve after the teaching-learning process.
💡 Testbook Style Key Point
The true success of school administration is measured by student achievement, skill development, and overall academic performance rather than physical appearance or individual relationships.
Why others are incorrect:
• Head teacher → Individual role, not full system performance
• Beautiful building → Infrastructure, not learning quality
• Teacher-student relation → Important but partial factor
