How were the tests in Rapid selected?

The cognitive areas assessed by the subtests in Rapid Dyslexia Screening (see Table 1) assess phonological and memory skills that are known to impact on literacy.

Table 1. Areas assessed by Rapid Dyslexia Screening

Subtest Age range Cognitive area assessed
Rhymes / Word chopping / Segments 4:0 – 15:11 Phonological processing
Races / Mobile phone 4:0 – 15:11 Auditory sequential memory
Crayons / Funny words / Non-words

4:0 – 7:11

8:0 – 15:11

Visual-verbal integration memory

Phonic skills

In order to allow for natural development in the component skills as children get older and ensure that the test gives accurate results, the content of each of these subtests varies according to the age of the child, although the underlying cognitive processes are essentially the same.

The subtests for each age group are shown in Tables 2 to 4.

Table 2. Rapid subtests for students aged 4:0–7:11

Subtest Description
Rhymes Rhymes is a test of phonological awareness, involving detection of rhyme (for students aged 4–6) and rhyme and alliteration (for students aged 7).
Races Races is a test of auditory sequential memory using animal names. It starts with lists of three animals and progresses up to four animals (for students aged 4–6) or five animals (for students aged 7).
Crayons Crayons is a test of visual-verbal sequential memory, in which students are required to remember the order that different coloured crayons are presented in.

Subtest Description
Word chopping Word chopping is a test of phonological processing using syllable and phoneme deletion.
Mobile phone Mobile phone is a test of auditory sequential memory using digit span.
Funny words

Funny words is a test of phonic skills involving non-word reading.

Subtest Description
Segments Segments is a test of phonological processing using syllable and phoneme deletion.
Mobile phone Mobile phone is a test of auditory sequential memory using digit span.
Non-words Non-words is a test of phonic skills involving non-word reading.
