Atmosphere and caring teachers at special schools more important to parents of children with SEN than educational standards, study shows

A study found that parents prioritize atmosphere and teacher approach over academic standards when selecting a special school for their child. High-quality inclusive education provision means a sense of belonging, social acceptance, and individualized curriculum. Only a minority reported experiencing 'hard choice' due to limited options.
