5 Strategies That Guarantee A* Evaluation Every Time
By Mr K – World’s Highest A-Level Psychology Scorer

The Truth About AO3 Evaluation

“I know all the content perfectly, but I keep losing marks on evaluation. How do I get those Level 4 marks?”

After analyzing every AQA mark scheme from 2015-2024, I’ve identified the exact 5 evaluation strategies that appear in 90%+ of top-level responses. Master these, and A* evaluation becomes predictable.

The 5 Essential AO3 Strategies

These strategies appear consistently across all psychology topics and represent the difference between average and exceptional evaluation. Each strategy includes specific examples, key talking points, and SO statements that examiners expect to see.

Strategy 1: Research Evidence Analysis

What it is: Using specific studies to both support AND challenge theories/explanations

Key Talking Points:

  • Supporting evidence: Name specific studies that validate the theory
  • Contradicting evidence: Studies that challenge or limit the explanation
  • Mixed findings: When research shows inconsistent results
  • Research quality: Whether evidence comes from reliable, well-designed studies
Example – Social Influence:
Asch’s conformity research provides strong supporting evidence for normative social influence. His baseline study found 37% conformity to obviously incorrect line judgments, with post-experimental interviews revealing participants conformed to avoid social rejection and embarrassment.
This supports NSI theory by demonstrating that people will conform against their better judgment purely to gain social approval, validating the idea that our fundamental need for acceptance can override logical reasoning in group situations.
Contradicting Evidence:
However, Perrin and Spencer (1980) found only 1 conforming response in 396 trials when replicating Asch’s study with British engineering students, suggesting that conformity behaviour may be historically and culturally specific rather than universal.
This challenges the universal validity of NSI, suggesting that conformity theories may be bound to specific historical periods (1950s McCarthyist America) and cannot reliably predict behaviour in contemporary individualistic societies, limiting their explanatory power for modern social influence phenomena.
Strategy 2: Methodological Evaluation

What it is: Critiquing research methods while understanding their purpose and limitations

Key Talking Points:

  • Ecological validity: Do lab findings apply to real-world situations?
  • Population validity: Can findings generalize beyond the sample studied?
  • Temporal validity: Do older studies still apply to contemporary behaviour?
  • Internal validity: Are there confounding variables affecting results?
  • Measurement issues: Are the ways behaviour is measured appropriate?
Example – Attachment:
The Strange Situation procedure has been criticized for its lack of ecological validity. The laboratory setting with unfamiliar surroundings, one-way mirrors, and structured separation episodes may not reflect how attachment behaviors manifest in naturalistic environments where children and caregivers interact daily.
This reduces confidence in attachment classifications because children’s behavior in artificial lab settings may not accurately represent their real attachment security, potentially leading to misclassification of attachment types and inappropriate interventions in clinical or social work contexts.
Counter-argument:
However, the controlled nature of the Strange Situation allows for standardized assessment and reliable measurement of attachment behaviors that would be impossible to observe systematically in natural settings, providing essential scientific rigor for attachment theory.
This methodological strength enables cross-cultural research and systematic comparison of attachment patterns, making it possible to identify universal vs culture-specific attachment behaviors and develop evidence-based interventions for improving parent-child relationships.
Strategy 3: Comparison to Alternative Approaches

What it is: Contrasting your topic with different psychological perspectives or explanations

Key Talking Points:

  • Biological vs psychological: Nature vs nurture explanations
  • Individual vs situational: Person factors vs environmental influences
  • Cognitive vs behavioural: Mental processes vs observable actions
  • Reductionist vs holistic: Simple vs complex explanations
  • Historical vs contemporary: How approaches have evolved
Example – Schizophrenia:
The dopamine hypothesis offers a biological explanation focusing on neurotransmitter dysfunction, while family dysfunction theories propose psychological causes through communication patterns and emotional expression. These approaches differ fundamentally in their assumptions about causation and treatment implications.
This highlights the nature-nurture debate in schizophrenia research, where biological explanations lead to drug treatments while psychological approaches emphasize family therapy, suggesting that an integrated bio-psycho-social model may be necessary for comprehensive understanding and effective treatment of this complex disorder.
Gender Research Example:
Social learning theory’s emphasis on observational learning and modeling contrasts sharply with biological explanations of gender that focus on hormone influences and evolutionary adaptations, representing fundamentally different views of gender development.
This comparison reveals that gender development likely involves complex interactions between biological predispositions and social learning, suggesting that purely environmental or purely biological explanations are overly reductionist and that contemporary gender identity formation requires consideration of both influences plus individual agency and cultural context.
Strategy 4: Real-World Applications & Implications

What it is: Demonstrating how psychological research translates into practical benefits and societal impact

Key Talking Points:

  • Therapeutic applications: How research improves mental health treatment
  • Educational implications: Impact on teaching and learning strategies
  • Legal system benefits: Improving justice and legal procedures
  • Social policy development: Informing government and institutional policies
  • Prevention programs: Using research to prevent problems before they occur
Example – Memory Research:
Research into eyewitness testimony has revolutionized legal practice through development of the Cognitive Interview technique. Based on context-dependent memory and multiple retrieval pathways, this method has increased accurate recall by up to 35% compared to standard police interviews.
This demonstrates the practical value of memory research in protecting innocent people from wrongful conviction while helping solve crimes more effectively, validating the real-world importance of laboratory memory studies and showing how psychological science can directly improve justice outcomes and public safety.
Attachment Application:
Bowlby’s attachment theory has directly influenced adoption and foster care policies, with placement decisions now considering attachment security and the importance of consistent caregiving relationships for child development and mental health outcomes.
This practical application has improved child welfare by ensuring that vulnerable children receive appropriate placements that support secure attachment formation, demonstrating how attachment research translates into evidence-based social policies that protect children’s long-term psychological development and reduce the risk of future mental health problems.
Strategy 5: Issues & Debates Analysis

What it is: Connecting your topic to broader psychological issues like determinism, culture, gender, and ethics

Key Talking Points:

  • Determinism vs Free Will: Are behaviors determined by factors beyond our control?
  • Cultural Bias: Do findings apply across different cultures and societies?
  • Gender Bias: Are there systematic differences in how research treats men and women?
  • Ethical Considerations: Are research methods and applications ethically justified?
  • Individual Differences: How do personality, age, and background affect findings?
Determinism Example – Obedience:
Milgram’s research suggests that situational factors can determine obedient behavior regardless of individual moral beliefs, implying that people have limited free will when faced with legitimate authority figures in hierarchical situations.
This raises profound questions about personal responsibility and moral accountability, suggesting that people may not be fully responsible for their actions in authoritarian contexts, which has important implications for legal systems and understanding compliance in institutions like military, medical, and corporate environments.
Cultural Bias Example – Conformity:
Bond and Smith’s (1996) meta-analysis found that collectivist cultures (Japan, Brazil) showed higher conformity rates than individualist cultures (USA, UK), suggesting that Asch’s original findings may not represent universal human behavior but rather Western cultural values.
This cultural bias limits the generalizability of conformity research and suggests that social influence theories developed in Western contexts may not apply to majority world populations, highlighting the need for cross-cultural research and culturally sensitive approaches to understanding social behavior in our increasingly globalized world.
Gender Bias Example – Depression:
Depression research has historically focused on female-typical symptoms (sadness, crying, withdrawal) while potentially overlooking male-typical presentations (anger, substance use, risk-taking), leading to systematic under-diagnosis in men.
This gender bias in diagnostic criteria and research focus may contribute to higher male suicide rates by preventing appropriate identification and treatment of depression in men, highlighting how research biases can have serious real-world consequences and emphasizing the need for gender-sensitive approaches to mental health research and practice.

Common Mistakes That Kill A* Evaluation

  • Generic criticism: “This study lacks ecological validity” (without explaining how or why it matters)
  • Missing SO statements: Identifying problems without explaining their significance
  • One-sided evaluation: Only criticizing without recognizing any strengths or applications
  • Wrong focus: Criticizing studies for things they weren’t designed to do
  • Surface-level analysis: Superficial critique without understanding research trade-offs
  • No topic connection: Generic evaluation that could apply to any psychology topic
