With handwriting being limitedly taught in schools; high intensity, summer handwriting camps may resolve the numerous handwriting rehabilitation referrals of school-aged children. To improve handwriting, a 5-day (3-hr/daily session) summer camp was created for children (ages 5-9 years old). Thirty children (ages 5-9) were given manuscript instruction and 16 children (ages 7-9) were given cursive instruction. Handwriting was assessed via the Test of Handwriting Skills: Bus (letter recall) and Horse (letter formation) subtests. Participants' manuscript and cursive skills significantly improved (p < 0.05) and the subtests positively correlated post intervention (p < 0.05). Thus, a high intensity, 5-day handwriting camp may improve handwriting skills.
