Swift and effective
adaptive computerised
assessment of verbal and
non-verbal skills
Lucid Ability
uses enjoyable and
stimulating activities
to assess verbal and
non-verbal reasoning
skills in the age range
4 - 16 years.
Easy administration
Lucid Ability is
available in three
versions, corresponding
to the age groups 4 - 8,
7 - 12, and 11 - 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).
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.
Unlike most other
ability tests, the
results are independent
of reading attainment,
and can be used equally
well with readers and
non-readers.
Instant graphical
reports
 Results
are available
immediately,
facilitating swift
decision-making. Results
are presented in a
graphical screen
display, which can be
viewed and printed out
immediately. Scores are
provided in three forms
making it easy for
teachers to use.
- Standard scores
- Centile scores
- Age equivalents
An overall measure of
General Conceptual
Ability (GCA) is also
provided; this is based
on an amalgamation of
scores from the verbal
and non-verbal tests and
is a useful estimate of
general intelligence. An
administrator's manual
accompanies the program,
which explains how to
interpret results and
their implications for
learning.
Standardisation and
validation
Lucid Ability has
been developed to the
highest psychometric
standards. Norms are
based on large-scale
national
standardisations and are
built into the program.
Lucid Ability has
been standardised using
a sample of over 2,300
children across the age
and ability range. The
children were carefully
selected from 24
different schools in
different parts of the
UK, in order to produce
norms that are
representative of the
national population aged
4 - 16 years.
Lucid Ability has
been validated against a
range of conventional
instruments for
assessing verbal and
non-verbal ability,
including Wechler
Intelligence Scale for
Children (WISC-III),
British Ability Scales
(Second Edition),
British Picture
Vocabulary Scale (Second
Edition), NfER-Nelson
Verbal and Non-Verbal
Reasoning Tests, and the
Matrix Analogies Test.
