What this dot point is asking
The SQA wants you to explain what political parties do, set out the ideology and key policies of the main parties, and explain how factions and the pull of the centre ground shape party policy. The course specification lets candidates study any political party with representation in the Scottish or UK Parliament; the major examples are the Conservatives, Labour, the Liberal Democrats and the SNP. Questions ask you to analyse party functions or evaluate claims about ideological change, so you need accurate policy knowledge and balanced judgement.
The answer
The role and functions of political parties
Party ideologies and key policies
Factions and the centre ground
This tension explains why a party's stated ideology and its actual policy can shift over time, and why "evaluate" questions ask whether parties have genuinely converged on the centre or remain ideologically distinct.
Examples in context
When a party rewrites its manifesto to broaden its appeal, it shows the pull of the centre ground and the search for the median voter, but the change is often resisted by a faction loyal to the party's traditional ideology. The contrast between a party favouring lower taxes and a smaller state and one favouring stronger public services and greater equality shows that genuine ideological differences persist. A party's selection of candidates and its leadership contests reveal the internal factional battles that shape policy. These examples let a Higher answer evaluate whether parties have converged on the centre or remain distinct rather than just describing what parties do.

SQA Higher 202120 marksEvaluate the view that the main political parties have moved towards the centre ground.Show worked answer →
A -mark essay: up to marks for knowledge and understanding and up to for analysis, evaluation and a sustained conclusion.
KU should set out each party's traditional ideology and recent policy positions, with examples of moves towards the centre and of shifts back to the left or right. Naming a party's policies precisely strengthens KU.
Evaluation marks come from weighing evidence of convergence on the centre against evidence of continued ideological difference and internal factional pressure, and judging how far the claim holds. A sustained conclusion lifts the answer.
SQA Higher specimen12 marksAnalyse the functions of political parties in a democracy.Show worked answer →
A -mark analysis question, roughly half KU and half analysis. Markers reward developed explanation, not a list.
KU should explain the functions: contesting elections and forming governments, representing interests, developing policy, recruiting and selecting candidates, and engaging citizens in politics.
Analysis marks come from explaining why these functions matter for democracy, for example how parties give voters a clear choice and link them to government, and judging their overall importance. A clear judgement lifts the answer.
