Evaluation Tool of Children's Handwriting: ETCH
Introduction to the ETCH
More about the ETCH
Research shows that children with good handwriting are able to advance to higher level writing tasks that require complex cognitive processes
Children who have difficulty with basic handwriting usually have challenges in academic performance
In the school system, handwriting is one of the most common reason for referral to OT
OTs determine which domains of handwriting are the most difficult and if there are underlying sensory, motor, cognitive, psychosocial, or other factors interfering with handwriting
Administration and Scoring Competence
Test should be administered by an OT, PT, general or special educator, child psychologist, or other childhood specialist
The examiner should have knowledge of typical/atypical child development, experience assessing children of all abilities, experience with standardized assessments, practice administering the ETCH, and education/experience about movement, sensorimotor, cognitive, and psychosocial behaviors
The administrator should practice administration and scoring on 3 children in grades 1-6 for each test (cursive and manuscript)
Scoring competencey is required, and there is a tutorial and competency quizzes in chapter 5 of the examiner’s manual
Evaluation Tool of Children's Handwriting, 1st Edition, 1995 by Susan J. Amundson, Ph.D., OTR/L
Ages 6 years 0 months to 12 years 5 months (1st - 6th grade)
Evaluates cursive and manuscript handwriting by looking at legibility and speed of handwriting
Assesses letter formation, spacing, size, and alignment
Also assesses components of handwriting such as pencil grasp and pressure, hand pressure, manipulative skills with the writing tool, and classroom observations
7 cursive writing tasks, 6 manuscript writing tasks, and items to assess handling of pencil and paper are included
Available from OT Kids for $150 and Therapro for $200
Administration Procedure
Examiner determines child's information and sets up the testing room to be well lit, with an appropriate size table and chairs, quiet and distraction-free, and charts with manuscript or cursive hidden from child's view
Examiner explains the purpose of the assessment and what will be happening during the testing time to the child
Examiner sits across the table or next to the child on the opposite side of his/her preferred hand
Examiner administers subtests in numeric order to the child
Administration should take between 15 and 30 minutes
Psychometric Properties
Scoring Procedure
So what should you remember?
The ETCH assesses handwriting legibility, speed, and related factors in children in 1st through 6th grade
It is a quick assessment: 15-30 minutes for administration and 10-20 minutes for scoring
Administration is fairly simple, but scoring and using the manual can be tricky
Adequate overall reliability, but use individual test scores with caution
Overall standardization - In between excellent and adequate
Interrater Reliablity - Acceptable
Test-Retest Reliability - Low
Content Validity - Adequate
Criterion Validity - No studies carried out
Concurrent Validity - Moderate
Overall Reliability - Adequate
Time is recorded for all tests
Use symbols and codes on writing samples
For IAB and II, place checks in boxes corresponding to symbols made on writing sample, starting with last letter/numeral and working backwards
For remaining tests, tally up legible words/letters/numerals, fill in appropriate boxes
Convert time in seconds to minutes using chart in manual
For III and IV, letter/min is determined by dividing the total letters in the task by time in minutes
For III through VI refer to charts for percentages
TOTAL scores - transfer "total legible" words/letters/numerals into chart
Add final two rows of "task" scores and put that number in "totals"
Divide attained total points by possible total points for the total legibility percentage
Our opinion.....
