Student Guidelines for the Doctoral Thesis

Doctoral Thesis

Your doctoral thesis is the culmination of your investment in advanced studies and rigorous research in your field of study. It is the pinnacle of your doctoral program, and the most far-reaching undertaking in your studies. Although the thesis is indisputably significant, it is also important to remember that the doctoral thesis is just one of many steps along your career path and should therefore be well-defined and manageable. 

At the University of Toronto, the term ‘thesis’ is generally used to refer to the culminating project for either a Master’s or a doctoral degree. At other institutions and in other countries, the term ‘dissertation’ is more commonly used at the doctoral level. This document uses the term ‘thesis’ to refer to a doctoral thesis, but your supervisor or department may prefer the term ‘dissertation’. 

Doctoral thesis writers have often written a Master’s thesis (or a Major Research Paper) earlier in their careers. A doctoral thesis will have elements in common with those projects while also needing to offer a higher degree of originality and a broader scope. 

The doctoral thesis has been historically written as a unified work, similar in form to a scholarly monograph; this traditional format remains the norm in some disciplines. In other disciplines, the traditional thesis has been replaced by a publication-based thesis in which a series of scholarly publications on the same research problem are combined into a coherent whole. Today, there is a growing acceptance of more flexible formats and structures that aim to enhance professional practice or that include creative scholarly artefacts such as film, audio, visual, and graphic representations. There is also growing recognition of the need to welcome Indigenous forms of knowledge building and dissemination. Regardless of format or structure, all doctoral theses must meet the fundamental requirements of demonstrating academic rigour and making a distinct contribution to the knowledge in your field.

The decision about the structure and format of the student’s doctoral thesis should be made by the supervisor and the supervisory committee members and be informed by the practices in the specific discipline and the student’s academic and professional goals. In some fields, the decision about structure and format is relatively easy to make while in others the decision requires careful consideration from all involved parties.

The following guidelines have been designed to help you and your supervisory committee by identifying the required academic criteria of the doctoral thesis and by describing the various available formats and structures.

Key Criteria of the Doctoral Thesis 

Regardless of the format of the doctoral thesis, certain criteria must be met. For your thesis to be acceptable, you must do the following:

• Demonstrate how your research makes an original contribution by advancing knowledge in your field
• Show a thorough familiarity with the field and an ability to critically analyze the relevant literature
• Display a mastery of research methods and their application
• Offer a complete and systematic account of your scholarly work
• Present the results and analysis of your original research
• Document your sources and support your claims 
• Locate your work within the broader field or discipline
• Write in a style that respects the norms of academic and scholarly communication 

Most doctoral writers understand that their thesis will need to meet these criteria without necessarily understanding how they will do so. A central element of writing a thesis is coming to understand how to write an extended text that meets these criteria. With guidance—from your committee, from your peers, from institutional writing support—and with your own growing expertise as a writer, these criteria will ultimately help you to understand when you have met your thesis writing goals.

Formats of the Doctoral Thesis 

Traditional Thesis

The traditional, or monograph-style, thesis format reflects the original conception of a thesis as a “book” presenting the candidate’s research project. The traditional format is organized as a single narrative describing the research problem, the context of the research, the methods used, the findings, and the conclusions. The organization of a traditional thesis is generally organic. If the thesis deals with experimental research, it may be structured with an introductory chapter, a literature review chapter, a method chapter, some number of findings chapters, and a discussion/concluding chapter. If the thesis is based on non-experimental research, the form is likely to be determined by the exigencies of the particular topic. After doctoral studies are complete, a traditional thesis will often be revised into a scholarly monograph or a number of research articles, but the form in which it is presented for the final oral exam is not itself intended for publication. This style of thesis remains the norm in the Humanities and in many Social Science disciplines.

Publication-Based Thesis

The publication-based thesis (PBT), also referred to as the manuscript or article-based thesis, is a coherent work consisting of a number of scholarly publications focusing on the same research problem. The PBT, which takes many forms, generally includes an introductory section, the publishable manuscripts, and a cumulative discussion or conclusion chapter. To promote coherence, the introduction and cumulative concluding chapters clearly explain how these separate manuscripts fit together into a unified body of research. The opening and closing chapters—which act as bookends to the publishable articles—are integral to the purpose of these theses. In these sections, the writer will set out the broad contours of the problem and its significance, review the relevant literature and contextualizing material, and draw the ultimate conclusions about the implications of the whole research project.  As the PBT is a relatively new type of thesis structure designed to meet different professional demands, its form is necessarily different in different contexts. For instance, in some fields, the articles may appear in the thesis in their precise published form; in others, the articles may need to be adapted to better serve the needs of the full thesis. You and your committee will need to establish a clear understanding from the outset about the internal structuring of the PBT. 

Although departmental requirements and norms may vary, below are some general guidelines that may be helpful for those writing PBTs.  

• The number of articles required for inclusion is usually three, although the number depends on the articles’ scope, scientific quality and significance, and publishing forum, as well as the author’s independent contribution to any co-authored articles included in the thesis. 
• Publication of manuscripts, or acceptance for publication by a peer-reviewed journal, does not guarantee that the thesis will be found acceptable for the degree sought. 
• Published-based theses may include published, in press or in review manuscripts or articles that have not yet been submitted for publication. Normally, the thesis and examination committees must deem the articles as publishable if the articles are not published at the time of defence.  
• In some departments, the publication-based thesis includes each individual manuscript in a form that is identical to the published/submitted version, including the reference list.  In other departments, students are permitted or required to adapt the articles into a form more suitable for inclusion in the thesis. Please check with your department about the expectations. 
• Publication-based theses can include co-authored publications and, in such cases, a detailed statement on individual student contributions to each article must be clearly articulated. Students are strongly recommended (and, in some units, required) to have their contributions approved by the authors of the articles in question.
• No two student theses will be allowed to be identical.
• In the case of multiple-authored articles, the expectation is that the thesis writer will be the first or co-first author. In rare cases, a supervisor may decide that a paper can be included when the thesis writer is not a first author, provided that their contribution to the paper is substantial. In all cases, the parts of the PBT that are not written for publication (the Introduction, Discussion, Conclusions and Future Recommendations chapters) must be entirely the work of the thesis writer.

Multimodal Thesis 

All doctoral theses must contain a written component; however, other elements may be included in addition to the written text. Some examples of other elements that may be included with the written text are films or videos, electronically interactive word/image-based texts, poems, novels or sections of a novel, play scripts, short stories, documentation of performances, or pieces of art. In multimodal theses, the creative element should be integrated into the theoretical context in order to show explicitly how the thesis, as a whole, leads to new insights and contributions. In all other respects, the thesis must conform to the same standards required for all doctoral theses. It should make an original contribution to knowledge, demonstrate appropriate research methods and training, and be worthy of publication in whole or in part.

Portfolio Thesis

The portfolio thesis is a form of thesis in which a certain amount of publishing will “equal” a thesis, without requiring a separate text to be written. This type of thesis is also known as a stapler thesis or a Ph.D. by publication, a name that highlights the absence of an actual thesis. This form of thesis is currently rare at the University of Toronto.

Professional Doctoral Thesis in Practice  

At the University of Toronto, the professional doctoral thesis in practice includes the identification and investigation of a problem in practice, the application of theory, research and policy analysis to the problem of practice, translating research into practice, and a proposed plan for action to address the problem of practice. The professional doctoral thesis in practice is expected to have meaningful generative impact on practice and policy.
