Diagnostic Test of Word Reading Processes

A standardised reading test that assesses regular words, exception words and non-words, thus providing diagnostic information to guide intervention.

The test comprises 90 items divided as follows:
• 30 exception words which provide a measure of lexical-semantic processes;
• 30 non-words which provide a measure of phonological recoding processes;
• 30 regular words which can be read by either process.

It is the first test to:
• Match words in the regular word and non-word sets by compiling non-words from segments of regular words.
• Match the regular and exception word sets according to their frequency of occurrence in books read by school children in the UK.
• Provide normative data obtained from a large and representative sample of children from Reception/P1 to Y7/S1 in schools in England.

Quick and easy to administer, score and interpret, the Diagnostic Test of Word Reading Processes makes available to teachers a diagnostic tool that has long been used in research studies, and that enables precise specification of the areas of difficulty experienced by individual children in developing fluent and automatic word reading.
