The CTMT is an invaluable, meticulously-constructed, nationally-normed, reliable and valid new psychometric instrument. It is extremely sensitive to neurological insult, disease, injury or dysfunction, which is often present in individuals with learning disabilities.

The CTMT is a new assessment, based on time-tested techniques. It is a standardized set of five visual search and sequencing tasks that are heavily influenced by attention, concentration, resistance to distraction and cognitive flexibility (set shifting).

Its primary uses include the evaluation and diagnosis of brain injury, and other forms of central nervous system compromise. More specific purposes include the detection of:

  • Frontal lobe deficits
  • Problems with psychomotor speed
  • Attention
  • Visual search and sequencing
  • Impairments in set shifting

Neuropsychologists; clinical, counseling, school and pediatric psychologists; occupational therapists; speech and language professionals; physical therapists, and others interested in objective testing of functionality in brain-behavior relationships would benefit from the CTMT.

The basic task of trail-making is to connect a series of stimuli (numbers expressed as numerals or in word form, and letters) in a specified order, as fast as possible. The score derived for each trail is the number of seconds required to complete the task. The five trails are similar, but also different, in some significant way.

It provides clinicians and research workers with a hierarchy of specific, as well as global summary measures, that operationally define important basic and complex components of executive function.

The Five Trails

  • Trail 1 — Draw a line to connect the numbers 1 through 25, in order. Each numeral is contained in a plain circle.
  • Trail 2 — Draw a line to connect the numbers 1 though 25, in order. Each numeral is contained in a plain circle. Twenty-nine empty, distractor circles appear on the same page.
  • Trail 3 — Draw a line to connect the numbers 1 through 25, in order. Each is contained in a plain circle. Thirteen empty, distractor circles, and 19 distractor circles containing irrelevant line drawings, appear on the same page.
  • Trail 4 — Draw a line to connect the numbers a through 20, in order. Eleven of the numbers are presented as Arabic numerals (e.g., 1, 7); nine numbers are spelled out (e.g.; Ten, Four).
  • Trail 5 — Draw a line to connect, in alternating sequence, the numbers 1 through 13, and the letters A through L. The subject begins with 1, then draws a line to A; proceeds to 2, then B, etc. Fifteen empty distractor circles appear on the same page.

The CTMT was standardized on a nationwide sample of 1,664 persons whose demographic characteristics match the U.S. 2000 census data. Reliability scores for each individual trail is high, and the composite score has a reliability coefficient of .90 or higher at all ages. Normative scores are provided in the form of T-scores, having a mean of 50 and a standard deviation of 10, along with their accompanying percentile ranks.

The CTMT Kit includes the Manual and 10 Record Booklets.
