Introducing PAA's LUCID, a portfolio of fast, accurate, digital assessments designed to screen and diagnose students with suspected specific learning difficulties.

Designed to complement PAA's YARC, with LUCID you can screen whole classes for dyslexia, discover specific cognitive strengths and weaknesses of this population or predict student abilities across their school journey. LUCID gives special education and learning support teachers the tools they need to shine a light on student learning.

These tools feature: Computer delivery, instant reports, brief as well as detailed testing and assessments, unlimited use licencing.


Quick, whole-class dyslexia screening

Ages: 4-15 years

Time: 15 minutes


  • Phonological processing (4-15 years)
  • Working memory (4-15 years)
  • Phonic decoding skills (8-15 years)
  • Visual-verbal integration memory (4-7 years)

RAPID is the solution for quick class screening for dyslexia or literacy learning difficulties in students in Pre-Year 1 to Year 9. It has three enjoyable and non-threatening tests that are sensitive cognitive indicators of dyslexia/a specific learning disability.

Each screening component has been individually standardised to maximise accuracy in detecting dyslexia and to prevent children 'slipping through the net'.

Reports include a clear indication of the probability of dyslexia and are available immediately after testing.

Lucid CoPs

Child-friendly early dyslexia screening

Ages: 4-8 years

Time: 45 minutes


  • Phonological Awareness (4-8 years)
  • Phoneme Discriminator (4-8 years)
  • Auditory Short Term Memory (4-8 years)
  • Visual Short Term Memory (4-8 years)
  • Visual and Verbal Sequencing (4-8 years)

CoPs is a leading assessments system for children aged 4-8 and is currently used in over 6,000 schools in the UK and around the world. CoPs can help teachers identify dyslexia and many other cognitive difficulties that can interfere with a child's learning.

CoPs comprises nine tests of fundamental cognitive skills that underpin learning. Each test is presented as an attractive and enjoyable game that takes about five minutes. Results, in the form of graphical profiles and individual response records, clearly show children's strengths and weaknesses. Percentiles, standard scores and age equivalent scores are provided, helping to identify potential problems at an early stage.

Lucid LASS

Identify dyslexic tendencies & other learning needs

Ages: Primary (4-11 years), Secondary (11-15 years)

Time: 45 minutes


  • Visual memory
  • Auditory-verbal memory
  • Phonic reading skills
  • Phonological processing ability
  • Single word reading
  • Sentence reading
  • Spelling
  • Reasoning

LASS is a multifunctional assessment system designed to highlight differences between actual and expected literacy levels. LASS is adaptive, so assessments are as brief as practicable without losing their accuracy. It is available in two versions: Primary for ages 8-11, and Secondary for 11-15.

Reports show percentiles, standard scores and age equivalents (including reading and spelling ages). Results show children's strengths and weaknesses in comparison with (UK) national norms. Use of a standardised graphical profile makes it easy to spot students who are underperforming.

Any difficulties of a dyslexic nature or caused by underlying cognitive problems in phonology and/or memory can be quickly identified. Assessment can be carried out on a regular basis to monitor progress.


Evaluate the speed & efficiency of working memory

Ages: 7-16 years

Time: 20-30 minutes

Tests: RECALL consists of three subtests

  • Phonological loop - assessed by a word recall test
  • Visuo-spatial sketchpad - assessed by a pattern recall test
  • Central executive function - assessed by a counting recall test

The program also measures the speed and efficiency of working memory (Processing speed).

RECALL swiftly identifies students who require classroom intervention strategies to help them to learn effectively because of working memory difficulties.

RECALL assesses the fundamental working memory functions identified by leading international researchers including Professor Alan Baddeley. It's easy to use, fully automated, requires minimal supervision and needs no input from the teacher.


Quick & effective adaptive assessments of verbal & non-verbal skills

Ages: 4-16 years

Time: 15-20 minutes

Lucid Ability uses enjoyable and stimulating activities to assess verbal and non-verbal reasoning skills in the age range 4-16 years. Each test automatically adapts to the child's individual ability level, making assessment very time-efficient and easy to administer. The total assessment time is about 15-20 minutes (conventional assessments of equivalent quality can take 2-3 times longer).

This assessment is suitable for non-readers.

For younger children (age 4-8 years) verbal ability is assessed by means of a picture vocabulary task, and non-verbal ability by means of a mental rotation game. For older children (age 7-16 years) verbal ability is assessed by means of conceptual similarities task, and non-verbal ability by means of a matrix problem-solving task. The tests do not require reading skills as the computer will read aloud any words that appear on screen if the child wants this.

Results are available immediately, facilitating swift decision-making. Results include standard scores; percentile ranks and age equivalents for both verbal and nonverbal reasoning as well as a composite measure of General Conceptual Ability (GCA).
