The taxonomy of school refusal - from school phobia to truancy - is complicated , and it has changed over time .
拒学症的分类较复杂，有些是对学校的恐惧，也有些是为了逃学，而且也在不断变化。
We don 't allow that kind of truancy , so it 's not clear why we should put up with such poor teaching .
我们不能放任这种旷课行为，所以不清楚为什么我们应该忍受如此差的教学质量。
And there is overlap , the experts point out : a child who misses a great deal of school for reasons that look like truancy may become increasingly anxious - and embarrassed - about going back .
Since 1993 , a system of " league tables " -- comparative tables which ranks schools according to public examination results , truancy rates , destination of school levers , and so on -- is published and schools are ranked according to the success of their pupils in reaching national targets .
