| Criteria / weighting (%) | 7 | 6 | 5 | 4/3 | 2/1 |
| 1. Describe the aims of the practice, facilities used and operating parameters (10%) | Description is clear, concise, with all aspects. | Description is clear with 1 or 2 aspects missing | Description is with gaps and 3 or 4 aspects missing | Description is patchy with many aspects missing | Description is unclear and most of the aspects missing |
| 2. Present the results for each test (CNT & EBSD) (10%) | All results are presented, correct, complete and accurate | Most results are correct with 1 or 2 mistakes or errors | Most results are correct with 3 or 4 mistakes or errors | The result of one test (CNT or EBSD) is basically correct but many errors in the other one | Result is incorrect and incomplete |
| 3. Interpretation of CNT characterisation results. (35%) | Tube diameter and wall thickness from TEM, contaminants and qualitative from SEM, full interpretation from Raman. | Missing one or two aspects in interpretation. | 3 or 4 aspects missing or mistaken. | Limited interpretation based on the extent of information available. | Interpretation is substantially incorrect or incomplete. |
4. Compare the strengths of each technique used
in characterization of CNT(20%) | Comparison demonstrates clear understanding of the principles of each technique, and their value in the characterisation process. | Description is clear with 1 or 2 aspects missing | Description is with gaps and 3 or 4 aspects missing | Description is patchy with many aspects missing | Description is unclear and most of the aspects missing |
| 5. Determine the grain size from the EBSD and use H-P equation to determine the yield strength. Describe the texture of the tested material. (25%) | Grain size measured by repeatable technique. Calculation complete and correct. Reasoned description of microstructure based on EBSD data. | Most of the exercise correct, but there are 1-2 errors/omissions. | Most of the exercise correct, but there are 3-4 errors/omissions. | Half of the exercise completed correctly, but major omissions/errors in remainder. | Results are substantially incomplete or incorrect. |
