Staffing Pattern For Itinerant Teacher of Students with Visual Impairments

(Adapted from the Iowa Rules for Special Education)

When caseload sizes for itinerant teachers of students with visual impairments are not specified, it is recommended that the maximum caseload be established at 10 full-time equivalents (FTEs) with appropriate adjustments made through application of the formula specified for the following three factors:

  1. the number of students receiving direct services
  2. the number of students receiving consultation services
  3. average daily amount of time spent traveling.

While professional services and traveling time are qualitatively equivalent, both factors must be considered in applying the formula below.

Use the following formula to calculate caseload size for itinerant teachers:

It is [the State of Iowa's] recommendation that the maximum caseload for itinerant teachers of students with visual impairments be established at 10 full-time equivalents (FTEs) with appropriate adjustments made through the following formula.

Formula:

  1. Count each student receiving direct services as 1 FTE regardless of the amount of contact time.
  2. Count 5 students receiving consultative service as 1 FTE, using a fraction if necessary.
  3. Calculate the total number of hours spent traveling in performance of job duties during a typical week and divide by 5 to get the average daily amount of time.
  4. Count 1 hour of average daily traveling time as 1 FTE using a fraction if necessary.
  5. Add the numbers from (1),(2), and (4), above for the total FTEs.

The total FTEs should not exceed 10 for one full-time itinerant teacher of students with visual impairments.

Other factors influencing caseload size which are built into the formula include activities such as parent conferences, pupil staffings, consultation, assessment, evaluation, observation, records, and correspondence. Also included are the frequency and duration of contacts with students receiving direct services, time for professional development, and materials preparation.-
