Although some preparation programs require that students complete as many as 600 clinical training hours through student teaching, other programs — which are all low - quality alternative certification programs — report that their students did not complete any clinical training hours.25 Even the most intensive teacher preparation experiences pale in comparison with the 10,000 hours of deliberate practice that researchers say are needed to develop expertise in any given field.26 While there are isolated
examples of excellent clinical residency models that provide students with
ample time to practice their skills in a
classroom setting, 27 there is not an entire system that supports this approach.
