		+	{{short description\|Senior civil servant who heads the Assessments Staff of the United Kingdom's Joint Intelligence Organisation}}
		+
		+	The '''Chief of the Assessments Staff''' is a senior civil service post in the [[Cabinet Office]]'s [[Joint Intelligence Organisation]] (JIO). The postholder leads a team of analysts responsible for drafting all-source intelligence assessments for the [[Joint Intelligence Committee]] (JIC) and the [[National Security Council]].
		+
		+	The Assessments Staff draws on intelligence from [[MI5]], [[MI6]], [[GCHQ]], [[Defence Intelligence]] and other sources, together with diplomatic reporting and open-source material, to produce coordinated assessments on security, defence and foreign affairs issues.<ref>UK Government, [https://assets.publishing.service.gov.uk/media/5a7ce67ce5274a724f0be32d/0114301808.pdf National Intelligence Machinery] ''GOV.UK'', 2010.</ref><ref>UK Government, [https://www.gov.uk/government/people/madeleine-alessandri Dame Madeleine Alessandri DCB, CMG] ''GOV.UK'', accessed April 2026.</ref>
		+
		+	== Role and responsibilities ==
		+
		+	The Chief of the Assessments Staff directs the permanent Assessments Staff, a multidisciplinary team of analysts seconded from across government. The team prepares JIC papers that provide ministers and senior officials with timely, objective all-source assessments. The role reports to the [[Chair of the Joint Intelligence Committee]], who is also the head of the JIO and Professional Head of Intelligence Analysis.<ref>UK Government, [https://www.gov.uk/government/people/madeleine-alessandri Dame Madeleine Alessandri DCB, CMG] ''GOV.UK'', accessed April 2026.</ref>
		+
		+	The post has no operational or collection responsibilities; it is purely analytical and coordinative.
		+
		+	== Position in the intelligence community ==
		+
		+	The Chief of the Assessments Staff sits inside the Cabinet Office, not within any of the three intelligence agencies ([[MI5]], [[MI6]], [[GCHQ]]) or Defence Intelligence. The Assessments Staff acts as the central fusion and assessment arm of the UK intelligence community, ensuring that raw intelligence is turned into policy-relevant assessments for the Prime Minister and National Security Council. It works closely with the agencies but remains independent of them.

−	==Notes==	+	== Known holders ==
		+
		+	Few names of past Chiefs of the Assessments Staff are in the public domain because the post is not routinely announced and holders are career civil servants whose identities surface only in later appointments, organograms or public inquiries.
		+
		+	Known holders include:
		+	* Paul Rimmer (~2009–2012)
		+	* Robert Tinline (2017–2019)
		+	* Robert Harrison (August 2019–~2022)
		+
		+	== Why few names are public ==
		+
		+	The role is internal and low-profile. Unlike agency heads or the JIC Chair, appointments are not the subject of press releases. Names become known only when individuals move to other public roles or appear in official organograms or inquiry evidence.
