If practice is done quite intensively (3 months) then about 20-25 hours of practice will get most children typing by touch. 10-15 minutes, twice daily (morning and afternoon / evening) will get good results in 12 weeks. The school summer holiday is ideal for an intensive course, 30-45 mins twice daily will get most kids touch typing in 4-6 weeks, going back to school in September with a very impressive new skill – especially if no one else can do it!
