Speech and Language Therapist Interview Questions

The Health and Care Professions Council (HCPC) is the UK regulatory body for speech and language therapists (SLTs). HCPC registration is a legal requirement to practise as an SLT and protects the public by ensuring practitioners meet professional standards. Registration requires completing an approved degree, passing competency assessments, and declaring fitness to practise. Registered SLTs must renew registration every two years and provide evidence of continuing professional development and reflection. The HCPC maintains a public register, investigates fitness-to-practise complaints, and can remove individuals from the register. RCSLT membership (Royal College of Speech and Language Therapists) is a separate professional body offering support, training, and advocacy for SLTs.

Dysphagia is difficulty swallowing—a common consequence of stroke, neurological conditions, head & neck cancer, or ageing. SLTs assess swallowing using bedside screening (observation, water tests) and specialist imaging (FEES—flexible endoscopic evaluation of swallowing, or modified barium swallow). Assessment identifies whether food/liquid enters the airways (aspiration), which increases pneumonia risk. Management includes dietary modifications (thickened fluids, soft foods), swallowing exercises (oral motor exercises, head positioning), or transitioning to alternative nutrition (feeding tubes). SLTs work with nutritionists and medical teams to balance nutritional safety with quality of life. Many people value eating despite dysphagia; SLTs help families and clients make informed choices about safe eating strategies.

AAC includes all methods of communication beyond natural speech—from simple (pointing, drawing) to complex (computerised speech-generating devices). AAC users include those with severe communication impairments from stroke, motor neurone disease, cerebral palsy, severe head injury, autism, or progressive neurological conditions. AAC devices range from low-tech (picture boards, communication books) to high-tech (tablets with speech software, eye-gaze systems for those with limited movement). SLTs assess which AAC method suits the individual's motor abilities, cognitive skills, and communication needs. AAC is not a barrier to speech recovery; rather, it bridges communication gaps whilst someone recovers speech or manages permanent impairment. AAC devices enable participation in education, work, social activities, and family life.

Aphasia is a language disorder resulting from brain injury (usually stroke, head injury, or brain tumour). A person with aphasia may have difficulty speaking (expressive aphasia), understanding language (receptive aphasia), or both. They might struggle to find words, construct sentences, follow conversations, or read and write. SLTs assess language function using comprehensive assessments and design therapy targeting specific impairments. Therapy might involve word-finding exercises, sentence construction practice, or functional communication strategies (drawing, gesturing, using written cues). Recovery from aphasia involves neuroplasticity (the brain's ability to rewire); therapy is most effective in the first 3–6 months post-stroke but can continue longer. Many people recover considerable language function with intensive therapy and practice, though some permanent impairment may remain.

Stuttering is a fluency disorder characterised by repetitions, prolongations, or blocks (moments of silence) when speaking. It typically emerges in early childhood and can persist into adulthood. Stuttering has genetic, neurological, and psychological components. SLTs assess fluency patterns, impact on communication and emotional wellbeing, and associated difficulties (anxiety, avoidance of speech situations). Therapy approaches include fluency-shaping techniques (slowed speech, smooth transitions), stuttering modification (managing moments of stuttering rather than avoiding them), and psychologically informed approaches addressing anxiety and communication confidence. Effectiveness varies; some people achieve fluency control, whilst others learn to communicate effectively despite some remaining stuttering. Support groups and self-help strategies complement therapy. Early intervention in childhood offers the best long-term outcomes.

SLTs work in schools identifying children with speech and language impairments, providing direct therapy, and collaborating with teachers to support communication development across the classroom. Early identification (often ages 2–5) of speech delays, language disorders, or hearing difficulties allows early intervention, improving long-term educational and social outcomes. SLTs may deliver pull-out therapy (individual or small group sessions), deliver advice to teachers for classroom integration, and consult on classroom strategies supporting communication. SLTs advocate for specialist placements or additional support for children with significant needs. Speech and language needs are common (affecting 5–10% of children) and, when addressed early, reduce educational disadvantage, behavioural difficulties, and social isolation. School-based SLT services are increasingly integrated into educational psychology and special educational needs support.
