Reading puzzle

Surprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850.000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education wh ile in hospital. We also know there is only one hospital teacher to every 1,000 children in hospital.?

Little wonder the latest survey concludes that the extent and type of hospital t eaching available differ a great deal across the country. It is found that half the hospitals in England which admit children have no teacher. A further quarter have only a part-time teacher. The special children’s hospitals in major cities do best; general hospitals in the country and holiday areas are worst off.

Can it be inferred from the latest survey that about one-fourth of the hospitals have full-time teachers ??

Thanks in advance!
