Typically we can help predict the length of time in a program based on standardized testing results (psychoeducational testing results, not necessarily state standardized assessments). Our team researched the length of time it would take to see consistent growth in reading ability. There were many factors at play but overall we found that student's could expect to see around 8 Standard Score points of growth in a 6-month period with therapy occurring once to twice per week. There was not a statistical difference between students being seen once to twice per week.
