What this dot point is asking

The SQA wants you to describe the voting systems used in Scotland and the UK, explain their advantages and disadvantages, and analyse how each system affects representation, voter choice and the type of government that results. Voting systems are one of the most heavily examined topics in this section and a common 2020-mark essay.

The answer

First Past the Post

The Additional Member System

Of the 129129 MSPs, 7373 are constituency MSPs and 5656 are regional (list) MSPs, with seven list MSPs in each of eight regions.

How the systems shape government and representation

FPTP tends to manufacture majorities, giving strong but sometimes unrepresentative government. AMS spreads representation more fairly but makes single-party majorities rarer: the SNP has governed as a minority and, from 20212021, worked with the Greens under the Bute House Agreement (ended 20242024). The choice of system is a trade-off between strong, accountable government and fair, proportional representation.

Examples in context

The 20192019 UK general election shows FPTP at work: a clear Commons majority was won on around 4444 per cent of the vote, while parties with substantial vote shares spread thinly across the country won few seats. By contrast, the 20212021 Scottish Parliament election under AMS returned the SNP just short of a majority and gave the Scottish Greens eight list seats, enabling a power-sharing deal. Comparing the two elections lets a Higher answer show concretely how FPTP manufactures majorities while AMS distributes seats more proportionally and shapes coalition or minority government.

Try this

Q1. Describe two advantages of the Additional Member System. [4 marks]

  • Cue. It is broadly proportional so smaller parties win seats, and voters have more choice and more than one MSP to contact.

Q2. Explain why First Past the Post is often criticised as unrepresentative. [6 marks]

  • Cue. It is disproportionate, wastes votes, and lets a party govern on a minority of the vote while squeezing smaller parties.

SQA Higher 201820 marksEvaluate the effectiveness of First Past the Post in producing a representative parliament.
Show worked answer →

A 2020-mark essay: up to 88 marks for knowledge and understanding and up to 1212 for analysis, evaluation, structure and a sustained conclusion.

KU marks come from describing FPTP accurately (single-member constituencies, plurality winner) and giving real evidence, for example a UK government winning a Commons majority on around 4444 per cent of the vote in 20192019, or smaller parties such as the Greens and Reform winning vote shares far larger than their seat shares.

Analysis and evaluation marks come from weighing the trade-off: FPTP delivers strong single-party government and a clear constituency link, but is disproportionate, wastes votes and under-represents smaller parties. A direct judgement on effectiveness in producing a representative parliament, sustained throughout, is what lifts the mark into the top band.

SQA Higher 202112 marksAnalyse the advantages and disadvantages of the Additional Member System used for the Scottish Parliament.
Show worked answer →

A 1212-mark analysis question, roughly half KU and half analysis. Markers reward developed explanation of how AMS works and why its features help or hinder representation.

KU should cover the mixed structure (7373 constituency MSPs by FPTP plus 5656 regional list MSPs across eight regions, 129129 in total) and real outcomes such as Green MSPs winning list seats and the SNP governing as a minority.

Analysis marks come from explaining why broad proportionality and two-vote choice are advantages, while complexity, weaker single-party majorities and two classes of MSP are disadvantages. A judgement on whether the gains in fairness outweigh the costs is the discriminator.
