Being called to give evidence to a Parliamentary Select Committee is an important opportunity to influence public policy and hold decision-makers accountable. Whether you are representing your organization, professional body, or providing expert opinion, thorough preparation is key to making your testimony clear, credible, and impactful.
Here’s a step-by-step guide to help you prepare your evidence effectively:
- Understand the Committee’s Purpose and Inquiry Scope
Research the Committee: Find out which Select Committee you are appearing before (e.g., Public Accounts Committee, Home Affairs Committee) and their role.
Review the Inquiry: Read the terms of reference or the inquiry’s background document carefully. Understand what questions the committee is investigating.
Study Past Sessions: Review transcripts or recordings of previous evidence sessions to get a feel for the tone, style, and types of questions asked.
- Clarify Your Role and Key Messages
Define Your Position: Be clear whether you are giving evidence as an expert, stakeholder, organizational representative, or victim/witness.
Identify Your Core Messages: Summarize the key points you want the committee to remember — keep these concise and fact-based.
Align Your Evidence: Ensure your evidence directly relates to the committee’s inquiry questions and objectives.
- Prepare a Written Submission
Write a Clear Statement: Most committees expect a written evidence submission before the oral hearing. Make it structured, factual, and free of jargon.
Use Evidence and Data: Support your statements with data, research findings, case studies, or examples.
Address Potential Challenges: Anticipate possible questions or objections and address them proactively in your written evidence.
- Practice Your Oral Evidence
Prepare Brief Notes: Summarize your key points into bullet points for easy reference during the session.
Rehearse Answering Questions: Practice responding to likely questions, including challenging or unexpected ones.
Keep Answers Focused: Answer questions succinctly and avoid going off-topic.
- Understand the Formalities of the Hearing
Know the Format: Confirm whether the hearing will be in-person, virtual, or hybrid.
Arrive Early: For in-person hearings, arrive early to get comfortable with the setting and technology.
Be Polite and Professional: Address committee members respectfully and maintain a calm tone.
- Handling Questions Effectively
Listen Carefully: Take a moment to understand the question before answering.
Be Honest: If you don’t know the answer, say so, but offer to follow up if possible.
Stay On Message: Bring answers back to your core messages and avoid speculation.
- Follow Up After the Hearing
Provide Additional Information: If you promised further details or documents, send them promptly.
Request a Transcript: Obtain a copy of the official transcript to review how your evidence was recorded.
Engage with Outcomes: Stay informed about the committee’s findings and consider how you or your organization can respond or benefit.
Tips for Success
Be Clear and Concise: Committees value clear, straightforward communication over complex language.
