British Sign Language Receptive Skills Test

Information about the test

The British Sign Language Receptive Skills Test was originally developed by Ros Herman, Sallie Holmes & Bencie Woll in 1999. The test measures children's understanding of sign language grammar in sentences. Teachers and researchers use the test to assess a child's sign language development and check progress. If a child is not making good progress, the test can pinpoint areas of sign language for teachers to target. The test is for deaf children between the ages of 3 and 12 years who use sign language. It can also be used with older children whose sign language skills are delayed.

The original Receptive Skills Test was presented on DVD. We have updated the test so that children can carry it out on a computer or tablet via the test website. The project team is currently up-dating the test scores. This means that children who take the test can be compared with more recent test norms.

What does the test involve?

To do the test, children first name some simple pictures. Next, children watch sentences in BSL on the computer. For each sentence, the child chooses the picture that matches the meaning of the test sentence. When children start to find the test difficult, the test will automatically stop. The test takes about 20 minutes. At the end of the test, the teacher will receive a report with the child's test score which they can share with parents.

Before taking the test: Giving consent

Children normally take the test individually in school. Before starting the test, the teacher/researcher will explain to parents what is involved. Parents need to sign a consent form agreeing to their child taking the test. Parents can also consent to their child's information being used in research, like the age, gender and how long they have been signing, etc., including test results. Participation in research is optional.

Before starting the test: Information about children

Once parents have given their consent, the teacher/researcher will enter some background information about the child into the test website, e.g. age, language(s) spoken/signed, etc. Each child is given a project number to ensure that information about them is kept confidential. If you give your consent, the information will only be accessed by the project team - Ros Herman, Bencie Woll and Kate Rowley, and will be stored securely on the website database for at least 10 years.

What is the Test of Adult Speechreading (TAS)?

The Test of Adult Speechreading (TAS) is a computer-based assessment of silent speechreading in adults. It is a user-friendly, video-to-picture matching task where the adult sees a video clip and has to click on the picture (from an array of four) that matches what they saw. The TAS is easy to administer and provides a snapshot of speechreading ability in approximately 20 minutes. It has been specifically designed to be suitable for use with deaf adults. There are two speakers: a man and a woman. All videos were recorded audio-visually to ensure natural speech but played without sound to measure silent speechreading.

Who is the TAS suitable for?

The TAS has been standardised on deaf adults aged between 21 and 60 years old and hearing adults aged between 16 and 76 years old.

Who can administer the TAS?

The TAS has been designed to be administered by researchers or clinicians who have experience of working with deaf people. The experimenter enters participant details, delivers the instructions and guides them through the correct sections.

What is The ToCS?

The Test of Child Speechreading (ToCS) is an assessment of silent speechreading in children. It is a child-friendly, video-to-picture matching task where the child sees a video clip and has to click on the picture (from an array of four) that matches what they saw. ToCS is easy to administer and provides a snapshot of speechreading ability in approximately 20 minutes.

There are three core Subtests that measure speechreading skills at three different psycholinguistic levels: Words, Sentences and Short Stories. It has been specifically designed to be suitable for use with deaf children. There are two speakers: a man and a woman. All videos were recorded audio-visually to ensure natural speech but played without sound to measure silent speechreading.

Who is the ToCS Suitable for?

ToCS has been standardised on deaf and hearing children aged between 5 and 14 years old. The Word subsection has also been used with children as young as 3 years old.

Who can Administer the ToCS?

It has been designed to be administered by researchers or clinicians who have experience of working with children. The experimenter needs to enter participant details, deliver the instructions and guide them through the correct sections. With younger children it is advisable that the experimenter controls the play button to start the video clips.

What is the Nonsense Sign Repetition Test (NSRT)?

The NSRT is a computer-based assessment of nonsense sign repetition in children. It is a child-friendly, video repetition task where the child sees a video clip of a nonsense sign and has to copy exactly the sign that s/he saw. The NSRT is easy to administer and provides a snapshot of the child’s ability to process new signs in approximately 20 minutes. It has been specifically designed to be suitable for use with deaf children.

Who is the NSRT suitable for?

The test is for children between the ages of 3 and 11 years.

Who can administer the NSRT?

It has been designed to be administered by researchers or clinicians who have experience of working with children.
