Contribute to non intrusive investigations in archaeological operations
This element focuses on the skills needed to contribute effectively to non-intrusive archaeological investigations, including field walking and geophysical surveys. Learners will develop competence in preparing equipment, taking precise observations and measurements, and compiling accurate records and schedules that adhere to professional standards. Mastery of these tasks supports the production of reliable data without disturbing protected archaeological deposits.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The Qualifications Scotland Level 3 NVQ Certificate in Archaeological Practice is a vocational qualification that equips learners with the practical skills and knowledge required for professional archaeological fieldwork, including excavation, recording, and post-excavation analysis. It emphasises competency-based assessment in real work environments, covering health and safety, site interpretation, and the application of archaeological methods.
Topic Overview
The Level 3 NVQ Certificate in Archaeological Practice is a work-based qualification designed for individuals pursuing a career in archaeology, such as field technicians, surveyors, or finds specialists. It focuses on developing practical competencies in real-world settings, from initial desk-based assessments to excavation and post-excavation analysis. This qualification is part of the Qualifications Scotland Occupational Qualification framework, ensuring it meets industry standards and employer expectations.
The course covers a range of essential skills, including site identification, excavation techniques, recording methods, and the use of GIS and total stations. Health and safety is a critical component, as archaeological work often involves physical labour and hazardous environments. Students are assessed through a portfolio of evidence, observations, and professional discussions, making it ideal for those already employed or volunteering in the sector.
This qualification is vital because it bridges the gap between academic archaeology and practical application. It prepares students for roles in commercial archaeology, heritage management, and research, and provides a pathway to higher-level qualifications such as a degree in archaeology or a Level 4 NVQ. By mastering these skills, students contribute to the preservation and interpretation of our shared heritage.

Learning Objectives
What you need to know and understand
- Be able to prepare for investigation operations, Be able to observe and record measurements when implementing non-intrusive investigations, Be able to prepare records and schedules, Know how to implement non-intrusive investigations, Know the different techniques applicable to non-intrusive investigations, Know how to prepare records of non-intrusive investigations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating the ability to correctly set up and calibrate geophysical survey equipment according to manufacturer guidelines and site-specific requirements.
- Credit is given for producing a clear, legible, and accurately annotated field log that records environmental conditions and any potential obstructions.
- Assessors should look for evidence of a completed record schedule that correctly references spatial data and follows project documentation protocols.
- Evaluate the learner’s competence in identifying and selecting appropriate non-intrusive techniques based on the site context and investigation aims.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference your recorded measurements against project specifications; demonstrate this in your evidence by including a checksheet or verification log.
- 💡When preparing records, use the templates provided by your workplace or awarding body as they model the expected format and terminology.
- 💡In your reflective account or witness testimony, explicitly match each action to the relevant performance criteria to show comprehensive coverage.
- 💡Practice interpreting sample geophysical data sets to build confidence in distinguishing between archaeological features and modern disturbances.
- 💡Always use the correct terminology, such as 'context', 'cut', 'fill', and 'interface', to demonstrate your understanding.
- 💡In practical assessments, show your working and explain your reasoning, especially when recording or interpreting features.
- 💡Keep a detailed and organised portfolio of evidence, including photographs, sketches, and written records, as this is a key part of your assessment.
Common Mistakes
Common errors to avoid in your coursework
- Students often confuse non-intrusive techniques (e.g., magnetometry) with intrusive practices (e.g., test-pitting), leading to incorrect application in simulated tasks.
- A common error is failing to regularly check and record grid reference updates when moving survey grids, causing spatial data misalignment.
- Some learners neglect to document temporary obstructions (e.g., parked vehicles) in field notes, which can compromise subsequent data interpretation.
- Misinterpreting geophysical anomalies without understanding the underlying physical properties, resulting in inaccurate preliminary identifications.
- Misconception: 'Stratigraphy is the same as geology.' Correction: While both study layers, stratigraphy in archaeology focuses on human-made deposits and features, and their chronological relationships.
- Misconception: 'All finds must be kept.' Correction: Only finds that are stratified or have research value are retained; unstratified or modern material may be discarded after recording.
- Misconception: 'A context is just a layer of soil.' Correction: A context can be any single event, including cuts, fills, walls, or floors, and is not limited to soil layers.
Revision Plan
How to revise this topic in 1–2 weeks

- 3Week 3: Study post-excavation processes, including finds processing and basic identification of common artefacts.
- 4Week 4: Consolidate your knowledge by writing mock assessments and getting feedback from your assessor or peers.
Exam Question Types
How this topic typically appears in the exam
- 📋Short-answer questions on definitions, e.g., 'Define what is meant by a context in archaeology.'
- 📋Scenario-based questions, e.g., 'You are excavating a trench and encounter a feature. Describe the steps you would take to record it.'
- 📋Health and safety questions, e.g., 'Identify three hazards on an archaeological site and explain how to control them.'

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: During a fieldwalking survey, you collect 150 sherds of pottery from a 20m x 20m grid square. Calculate the density of finds per square metre, and explain how this data might be used to interpret the site.
- 1.Step 1: Calculate the area of the grid square: 20m x 20m = 400 m².
- 2.Step 2: Divide the number of sherds by the area: 150 / 400 = 0.375 sherds per m².
- 3.Step 3: Interpret: A density of 0.375 sherds/m² is relatively low, suggesting either a low-intensity occupation or a scatter from manuring. Compare with surrounding grid squares to identify hotspots of activity.
Question: A 6-mark question: Describe the process of creating a Harris matrix for a small excavation with the following contexts: topsoil (001), a pit cut (002), its fill (003), a wall (004), and natural subsoil (005). Explain the stratigraphic relationships.
- 1.Step 1: Identify the stratigraphic units: 001 (topsoil), 002 (cut), 003 (fill), 004 (wall), 005 (natural).
- 2.Step 2: Determine relationships: 001 is the latest and overlies all. 002 cuts into 005 and is filled by 003. 004 is built on 005 and is sealed by 001.
- 3.Step 3: Draw the matrix: Place 005 at the bottom. Above it, show 002 and 004 as separate contexts. 003 is above 002 (since it fills it). 001 is at the top, sealing all.
- 4.Step 4: Explain: The matrix shows that the pit (002/003) and the wall (004) are contemporary or at least both later than the natural, but their relationship to each other is not directly established unless there is a physical interface.
