The HL Triptych: Connecting Your Three Canvases
The HL Visual Arts course requires you to do more than just complete three separate tasks. You must weave a single, strong thread of investigation through your Comparative Study (research), Process Portfolio (experiments), and Exhibition (final artworks). This sustained investigation demonstrates a deeper, more mature artistic practice.
Think of yourself as a detective investigating a complex case. The Comparative Study is your background research on similar past cases and criminal methods. The Process Portfolio is your evidence board, where you pin up clues, test theories, follow leads, and document dead ends. The final Exhibition is your presentation in court, where you present a curated selection of the most compelling evidence to prove your case (your artistic intention) to the jury (the examiner).
- 1
Identify a core theme or conceptual concern that genuinely interests you. This will be the 'golden thread' that connects everything.
- 2
In your Comparative Study, select artists and artworks that directly inform or challenge your core theme, and explicitly state how this research will influence your own studio work.
- 3
Use your Process Portfolio to document the journey: show how your research from the CS leads to specific experiments, and how these experiments evolve towards your final artworks.
- 4
In your Exhibition, write a Curatorial Rationale that clearly explains the conceptual journey, referencing your research and developmental process to justify your final body of work.

Defining 'Sustained Investigation' and 'Breadth'
At its heart, a 'sustained investigation' is a journey of inquiry. It begins with a central question, theme, or concept that you explore over the two years of the course. 'Sustained' implies that this exploration is ongoing, evolving, and not a series of disconnected projects. 'Investigation' implies a process of research, experimentation, reflection, and resolution. 'Breadth', the specific HL requirement, means you must demonstrate this investigation across a wider range of materials, techniques, and conceptual viewpoints than at SL. You are expected to be more ambitious in your scope.
Sustained Investigation: A documented journey of inquiry that connects all three components. It should show a clear line of development from initial idea to final resolution.
Breadth: Evidenced by exploring a variety of media, processes, and forms. For example, exploring a theme through sculpture, digital media, and printmaking.
Depth: The rigour of your investigation. This is shown through in-depth research, critical reflection on failures and successes, and the conceptual complexity of your final works.
Synthesis: The ultimate goal. This is where your research (CS), process (PP), and outcomes (Exhibition) merge into a single, powerful statement of your artistic practice.
The Role of the Comparative Study (CS) as a Catalyst
Too often, students treat the Comparative Study as a separate art history essay. For the HL student, it is the intellectual and critical foundation of your studio practice. The artists and artworks you choose to analyse should be selected because they directly inform, challenge, or resonate with your own developing investigation. The key is to make these connections explicit, particularly in Criterion D: Making Connections. You must articulate how analysing another artist's use of colour, material, or composition has influenced a specific decision in your own work.
The Process Portfolio (PP) as the Narrative
The Process Portfolio is the story of your sustained investigation. It is the connective tissue that binds your research to your final artworks. For HL, your PP must demonstrate a wider breadth of experimentation. It should not be a random assortment of techniques; rather, it should show a purposeful exploration of different media and processes, all in service of your central inquiry. Use your annotations to create a clear narrative. Explain why you are trying a new technique, how it relates to an artist you studied in your CS, and what you learned from the experiment, even if it was a 'failure'.
Create 'connection screens' in your Process Portfolio. Dedicate a screen to a mind map or a short reflective text that explicitly links a CS artist, a series of your experiments, and a developing idea for an exhibition piece. Use arrows and annotations to visually and textually map the journey of an idea. This provides irrefutable evidence of synthesis for the examiner.
The Exhibition and Curatorial Rationale as the Synthesis
Your final exhibition is the culmination of your two-year investigation. The selection and arrangement of works should present a coherent body of work that tells a story. It should not feel like a collection of your 'greatest hits', but a purposefully curated group of works that, together, articulate your central theme. The Curatorial Rationale is your single most important piece of writing to articulate this synthesis. It is your opportunity to guide the examiner through your journey, explicitly stating the conceptual thread that unites the work and referencing the research and experimentation that led to the final outcomes.

Sample extract from a Comparative Study (Criterion D: Making Connections) for a student investigating 'The Grotesque Body'.
- 1
In analysing Jenny Saville's 'Propped' (1992), her confrontational use of scale and the visceral, almost sculptural application of oil paint directly challenged my own initial, more tentative approaches to figure painting. Saville's distortion of flesh, which serves to question idealised forms of beauty, provided a critical precedent for my own work. This analysis prompted a significant shift in my studio practice, documented in my Process Portfolio (screens 11-13), where I moved from precise charcoal drawings to large-scale, expressive oil paintings on unstretched canvas. I sought to emulate her method of building up and scraping back paint to create a sense of scarred, lived-in skin, directly informing the technical resolution of my exhibition piece, 'Carcass I'.
Sample extract from a Curatorial Rationale for a student investigating 'Urban Decay and Renewal'.
- 1
This exhibition, 'Concrete Palimpsest', culminates a two-year investigation into the cyclical nature of urban environments. My inquiry began with a formal and contextual analysis of Gordon Matta-Clark's 'building cuts' (explored in my Comparative Study), which revealed the potential for architecture to be a medium for sculpture. This critical research prompted a series of material experiments, documented in my Process Portfolio, where I explored casting techniques with concrete, plaster, and found urban detritus. The resulting body of work synthesises these threads: the sculptures, such as 'Strata (i-iii)', use layers of cast concrete to echo geological time within the city, while the accompanying photographic series documents the transient beauty of demolition sites. Together, the works aim to present a coherent vision of the city as a living organism, constantly being written over and erased, a concept that has been the sustained focus of my practice.

Sustained Investigation
An in-depth, evolving, and coherent exploration of a central theme, concept, or inquiry that connects the Comparative Study, Process Portfolio, and Exhibition. It is the hallmark of the HL course.
