Foundations and History
What forensic science is and is not, the questions it answers, and the long arc of its history from early toxicology and fingerprints to the modern laboratory.
Start module- What Forensic Science Is: Definition, Aim and ScopeForensic science applies the methods of natural science to legal questions; this topic unpacks its definition, four core questions, and limits.13 min
- A Short History of Forensic ScienceForensic science grew from isolated techniques into a coordinated discipline, from Song Ci's medieval Chinese text through Orfila, Bertillon, and Locard to DNA.14 min
- The Pioneers: Locard, Bertillon, Galton, Lattes, GrossGross, Bertillon, Galton, Locard, Lattes, and Osborn each gave forensic science a foundational method still visible in modern casework.15 min
Module 26 hrs3 topics
Core Principles
The ideas the whole discipline rests on: Locard's exchange principle, individuality and comparison, and the probabilistic reasoning behind every conclusion.
Start module- Locard's Exchange Principle and Trace TransferEdmond Locard's idea that every contact leaves a trace, and the modern science of how that trace transfers, persists, and is recovered at a crime scene.13 min
- Individuality, Identity and the Logic of ComparisonThe principle of individuality holds no two objects are exactly alike; this topic covers class-to-individual comparison and its modern limits.15 min
- Reconstruction and Probabilistic ReasoningForensic reconstruction infers events from evidence, never records them; this topic covers the hierarchy of propositions and likelihood ratios.16 min
Module 36 hrs4 topics
Branches of Forensic Science
A map of the disciplines, from the core lab sciences through the medical and behavioural fields to the digital, document and engineering specialities.
Start module- The Branches of Forensic Science: A MapForensic science is a family of specialisations, each a different lens on reconstructing events; this topic maps how the major branches fit together.11 min
- The Core Lab Sciences: Biology, Chemistry, PhysicsThe forensic laboratory sciences, biology and DNA, chemistry, and physics and trace examination, examine physical material from scenes and people.12 min
- The Medical and Behavioural Forensic SciencesPathology, toxicology, anthropology, odontology, entomology, and forensic psychology each answer a different question about a person or their behaviour.11 min
- The Digital, Document and Engineering SciencesDigital forensics, questioned documents, forensic engineering, fingerprints and biometrics, and ballistics examine man-made systems and records.12 min

The Forensic Process
How a piece of evidence travels from scene to courtroom: the lab workflow, triage, and the reference standards and controls that make a result trustworthy.
Start module- The Forensic Process: From Scene to CourtroomThis topic traces evidence's full lifecycle, from a first responder's arrival through recognition, collection, lab analysis, and courtroom testimony.14 min
- The Forensic Laboratory Workflow and TriageThis topic covers how a lab receives, logs, and triages evidence, the roles within it, backlog-driven prioritisation, and its quality checkpoints.13 min
- Reference Standards, Controls and Comparison LogicForensic comparison rests on known versus questioned samples and reference materials, since controls validate a result, not the measurement alone.14 min
Module 56 hrs3 topics
Laboratory Organisation
How forensic services are structured around the world, the Indian CFSL and SFSL system, and the international bodies that set standards.
Start module- Forensic Laboratory Systems: A Global OverviewForensic laboratory services range from centralised national institutes to police-embedded units and private markets, compared across the US, UK, and Europe.14 min
- The Indian Forensic Setup: CFSL, SFSL, DFSS, NICFSIndia's forensic infrastructure runs through the DFSS under the MHA, the CFSLs, State FSLs, NICFS, GEQD, mobile labs, and the new BNSS forensic-visit mandate.12 min
- International Bodies: INTERPOL, ENFSI, SWGs, OSACINTERPOL, Europe's ENFSI, the US Scientific Working Groups and their OSAC successor, and the ISO/ILAC framework set standards across forensic science.15 min
Module 66 hrs3 topics
Physical Evidence
The nature and types of physical evidence, the class versus individual distinction, and how the weight of evidence is judged.
Start module- Physical Evidence: Nature, Types and ClassificationThis topic covers what physical evidence is, how forensic scientists categorise it, and the practical logic behind prioritising material at a scene.15 min
- Class versus Individual CharacteristicsClass characteristics limit a source to a group while individual characteristics point to one origin, shown through fingerprints, firearms, and fibres.15 min
- Probative Value and the Weight of EvidenceThis topic covers what makes evidence probative, how relevance and prejudice trade off in admissibility, and likelihood ratios as a weight measure.16 min
Module 76 hrs3 topics
Crime Scene Basics
Securing and documenting a scene, the search and collection methods, and the chain of custody that holds the evidence together.
Start module- The Crime Scene: Types, Securing and DocumentationThis topic covers how crime scenes are classified, sealed, and recorded, including the three documentation methods required before evidence is touched.15 min
- Search, Collection, Packaging and PreservationThis topic covers the four search patterns, contamination-free collection principles, and the packaging rules that determine evidence survives to the lab.13 min
- Chain of Custody: What It Is and What Breaks ItThe chain of custody documents everyone who handled a piece of evidence from collection to court; gaps or tampering can exclude it entirely.14 min
Module 86 hrs3 topics
Law and the Courts
Where science meets the legal system: admissibility standards across jurisdictions and the role and duties of the expert witness.
Start module- Forensic Science and the Law: An IntroductionThis topic covers how forensic science meets the legal system: adversarial versus inquisitorial courts, the burden of proof, and the science-law certainty gap.14 min
- Admissibility: Frye, Daubert and Cross-Jurisdiction RulesCourts decide whether expert evidence is admissible through the Frye general-acceptance test, the Daubert factors, or the UK and India's own frameworks.14 min
- The Expert Witness: Role, Duties and TestimonyThis topic covers the expert witness's overriding duty to the court, independence from instructing parties, report writing, testimony, and its limits.16 min
Module 96 hrs3 topics
Ethics and Quality
The examiner's duty to the court, cognitive bias and the 2009 NAS report, and the quality systems that underpin reliable forensic work.
Start module- Forensic Ethics and the Duty to the CourtThis topic covers what objectivity, impartiality, and the paramount duty to the court demand of practitioners, and where those duties have failed.13 min
- Cognitive Bias and the 2009 NAS ReportContextual and confirmation bias distort forensic analysis, as Itiel Dror's experiments and the 2009 NAS and 2016 PCAST reports both concluded.14 min
- Quality Systems: ISO 17025 and AccreditationISO/IEC 17025 sets what a forensic laboratory must meet, how accreditation bodies assess compliance, and why it matters for court admissibility.14 min
Module 106 hrs2 topics
Inference and the Future
Error, uncertainty and the statistics of forensic conclusions, and the methods reshaping the field, from machine learning to rapid DNA.
Start module- Error, Uncertainty and the Statistics of Forensic ScienceForensic results carry error rates rarely explained in court; this topic covers likelihood ratios, the prosecutor's fallacy, and probabilistic reporting.17 min
- The Future of Forensic Science: AI, Databases, Rapid MethodsMachine learning, rapid DNA, expanding databases, and portable field devices are reshaping forensic science, alongside new validation and privacy gaps.16 min
