Frequently Asked Questions

Where does the Lexplore assessment take place?

Our assessment can be carried out within the school environment. We just recommend examiners set themselves up in a quiet room close to the class from where pupils will be leaving and re-joining their lesson.

Will results be affected if a pupil wears glasses?

Our technology is able to monitor eye movement through all glasses. We also ask examiners to let us know in the comment section of the results if a pupil was wearing glasses so we can ensure our machine learning models take this into account during their analysis.

Can a child sit the assessment if they are visually impaired?

So far we have been able to determine the reading attainment of pupils with many different visual impairments, and will continue to train our Machine Learning models as we encounter new data. The assessment has not only been able to identify those with optical impairments, but also those who may require reading glasses, based on their eye movement.

How long does the Lexplore assessment take?

We estimate that the assessment takes between two and five minutes per child depending upon their reading speed. This enables schools to quickly assess a large number of pupils without additional workload.

At what age can a child sit the Lexplore assessment?

At the minute we only assess children from years 2 to year 5, however, we plan to extend this once we have trained our machine learning models to analyse the reading attainment of older children with the same level of precision.

How many children can be tested in one day?

We encourage schools to aim to test around 40 pupils in one school day. As each test takes between two to five minutes this also allows plenty of time for pupils to leave and return to their lessons.

What if schools do not already have the hardware needed?

We would not expect schools to have many eye trackers lying around, so we include all hardware required in the cost of a first year license. We not only include the eye tracker and monitor required, but also all training and support.

How many times should pupils be tested in one year?

We recommend that all children are tested at the beginning and the end of the academic year, and that those at low or below average levels are tested again in the middle. Regular testing enables teachers to closely monitor reading progress and the outcome of targeted interventions for each child.

What is the Karolinska Institute?

The Karolinska Institute is not only Sweden’s largest centre of medical academic research, but also one of the world’s foremost medical universities. Within Sweden they offer the largest range of medical courses, and since 1901 their Assembly has selected the Nobel laureates in Physiology or Medicine.
