What is ISL?

ISL is the sign language of the Republic of Ireland, but it is also used in areas of Northern Ireland. ISL is a visual-gestural language with its own grammar and principles — all of which are entirely different from the grammatical structure of English.

Our Irish Sign Language Courses

Please note: ‘Guided Learning Hours (GLH)’ include assessment time, and additional study hours include homework, private study, and practice*.

Course aims and objectives 

Our Level 1 Award in Irish Sign Language (ISL) teaches learners to communicate using ISL. This course covers a range of topics that involve simple, everyday language use.

Qualification structure

The Level 1 Award in ISL qualification is divided into three units. You’ll need to complete and pass all three to achieve the full qualification. 

Through these units, you’ll cover an array of themes and topics, including:

  • Animals and Objects
  • Describing People
  • Directions
  • Food and Drink
  • Interest and Activities
  • Meeting People
  • Sharing Information
  • Transport
  • Using Numbers
  • Weather

If you are entirely new to ISL, we recommend covering ISL101 first, as ISL102 and ISL103 build on the content from ISL101. Once you have completed ISL101, you can proceed to ISL102 and ISL103 in any order.

Keep up your learning with ISL homework and resources

To support you on your ISL journey, we have some helpful homework packages and resources available. 

ISL homework is a comprehensive online library of video clips and support materials to help you understand the assessments you’ll be undertaking, develop your vocabulary and linguistics skills, and practice your receptive ISL skills from wherever you are.

With packages starting from just £36.00, it’s perfect for anyone studying towards an Irish Sign Language qualification.

What essential pre-qualification requirements do you need for the Level 1 award in ISL?

Enrolling in this course requires sufficient sight, manual dexterity, and the ability to carry out facial and body movements needed to produce and receive ISL. You do not need to know Irish to enrol, as this course is designed for complete beginners.

How will it be assessed?

To assess your understanding and ability to communicate using Irish Sign Language (ISL), you’ll complete three assessments as part of your ISL Level 1 course:

ISL101 is internally assessed by your teacher. This assessment involves a simple conversation between you and your teacher using ISL.

ISL102 is externally assessed by a registered examiner. You will take part in a 4–5 minute ISL conversation based on specific topics covered in the ISL102 unit.

ISL103 is also externally assessed and involves another 4–5 minute conversation. This assessment focuses on the themes and vocabulary introduced in the ISL103 unit.

Qualification aims and objectives

Building upon the knowledge and skills learnt in Level 1, the Level 2 Certificate in Irish Sign Language will allow you to communicate with Deaf people using ISL in various familiar contexts using lengthy and open-ended exchanges.

Using real-life routines and daily experiences, you will be able to communicate confidently using a sufficient grasp of ISL grammar. You will also learn some regional variations in ISL to strengthen your knowledge.

Qualification structure 

The Level 2 Certificate in Irish Sign Language is split into three units. You must complete and pass all three units to achieve your full Level 2 Certificate. 

You can technically complete the units in any order, but we recommend starting with ISL201 before completing ISL202 or ISL203.

What essential requirements do you need for a Level 2 certificate in ISL?

You must complete the Level 1 ISL course or equivalent before enrolling on Level 2 to ensure you have a solid grasp of the basics. You will also need sufficient sight, manual dexterity, and the ability to perform any facial and body movements needed to produce and receive ISL.

How will it be assessed?

The assessment for the Level 2 Certificate in Irish Sign Language involves a 3–5 minute recorded presentation in ISL, based on Theme 1: Everyday Conversation and one additional optional theme chosen in advance with your teacher. 

You will begin by fingerspelling your full name and signing the chosen theme—this part is not marked. The presentation is delivered to your teacher, with both of you fully visible on camera to ensure all ISL features can be clearly seen. The teacher may prompt you up to twice to help keep the presentation flowing, but cannot assist with signing. The presentation must stay on theme and be in ISL (not SSE). Recordings must be unedited, and assessments under three minutes or off-theme will result in a fail. Anything over five minutes will not be marked beyond that point.

Qualification aims

Designed for learners who have already completed ISL Level 2, the Level 3 Certificate in Irish Sign Language will allow you to understand and use varied ISL in a range of work and social situations. This course builds upon the basic knowledge and contexts introduced in Levels 1 and 2. 

By the end of this ISL course, you will be able to demonstrate competence at Level 3 of the UK Occupational Language Standards (CILT, 2010).

What essential requirements do you need for a Level 3 certificate in ISL?

You must complete your Level 2 ISL course or equivalent before enrolling on Level 3 to show that you have a solid grasp of the basics. You will also need sufficient sight, manual dexterity, and the ability to perform any facial and body movements needed to produce and receive ISL.

Qualification structure

The Level 3 Certificate in Irish Sign Language is split into three units. You must complete and pass them all to achieve the Level 3 ISL Certificate.

Each unit is assessed separately, and you can take the relevant assessments after each unit if you wish. However, we recommend taking all three assessments at the end when all teaching is complete.

How will it be assessed?

The Level 3 Certificate in Irish Sign Language is assessed through three externally marked components designed to evaluate both receptive and productive skills using varied ISL across a range of topics. The assessments include:

  • Formal Presentation (8–10 mins): Based on a topic provided by Signature (chosen from a set of three), candidates have 14 days to prepare. Candidates must deliver a clear ISL presentation including Deaf issues, with accurate sign order and Non-Manual Features (NMF). Pass mark: 60%.
  • Informal Conversation (10–12 mins): On the day of the assessment, candidates choose a different topic from another set of three provided by Signature. After 30 minutes of preparation (with internet access allowed), they engage in a natural conversation with their teacher. Pass mark: 60%.
  • Receptive Skills (approx. 10 mins): Candidates will watch a video clip divided into three parts and respond to ISL-signed questions by writing or signing their answers. The task evaluates comprehension of varied signed communication, including regional variations. Pass mark: 60%.

To pass the qualification, candidates must demonstrate strong ISL grammar, appropriate sign order, and consistent use of NMF across all tasks. Use of SSE or insufficient ISL features may lead to disqualification.

Qualification aims

Following the Level 3 Certificate in ISL, Level 4 will allow you to communicate independently at a more advanced level. The Level 4 Certificate in Irish Sign Language is particularly useful for those who regularly work with Deaf people, such as social workers, teachers, communicators, and volunteers. 

The Level 4 Certificate in Irish Sign Language will provide you with the advanced skills you need to expand your knowledge of ISL as a whole.

What essential requirements do you need for a Level 4 certificate in ISL?

To show proficiency, you must complete the Level 3 ISL course or equivalent before enrolling on Level 4. You must also have sufficient sight, manual dexterity, and the ability to perform any facial and body movements needed to produce and receive ISL.

Parts 1 to 4 involve internal assessments on linguistic analysis of phonology, morphology, syntax, and sociolinguistics, based on pre-recorded ISL discussions (minimum 5 minutes each), either provided by the candidate or chosen by the centre. 

These are marked by the centre and externally moderated by Signature, with all outcomes recorded on Candidate Assessment Record (CAR) forms. 

Part 5 is a 60-minute written exam, externally marked by Signature, with a pass mark of 75%. 

All internal assessments must be completed before the written exam, and if a candidate fails any part, they must resit Part 5 and resubmit evidence for Parts 1–4.

  • Enhance Communication: Learning ISL allows you to effectively communicate with Deaf and hard-of-hearing individuals, promoting inclusivity and understanding.
