Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for demonstrating correct selection and preparation of equipment and materials, such as specimen pots, fixatives, and labelling systems, in line with standard operating procedures.
Award credit for accurately labelling biopsy specimens with patient identifiers, specimen type, and date/time, cross-referencing with request forms to maintain traceability.
Award credit for safely handling and disposing of fixatives and biological waste, adhering to COSHH regulations and local safety policies throughout the preparation process.

Assessment Guidance

Guidance for achieving higher grades

💡Ensure your portfolio evidence clearly demonstrates adherence to standard operating procedures at every stage, from specimen reception to handover.
💡In knowledge-based questions, relate your answers to real-world scenarios, referencing health and safety legislation (e.g., COSHH, HASAWA) and quality management principles.
💡When observed, verbalise your actions to reassure the assessor of your understanding of the rationale behind each step, particularly regarding infection control and specimen integrity.

Common Mistakes

Common errors to avoid in your coursework

Misidentifying or mislabelling specimens, leading to potential patient misdiagnosis or lost samples.
Inadequate fixation due to incorrect fixative-to-tissue ratio or insufficient immersion time, compromising downstream histological analysis.
Failing to wear appropriate personal protective equipment (PPE) or not following spillage procedures when handling hazardous chemicals like formalin.
