Derived Grade Procedure
Retention of Student Work
Strategies for success:






Have a set time for home learning (usually 20 to 25 min each day)
Complete home learning and hand in assignments on time
Put time into studying for assessments
Catch up work missed through absence
Monitor own achievement
Positive attitude
Externally Assessed Topics:
Achievement standards 2.3, 2.4 and 2.6 are assessed through written exam at the end of the year
Internally Assessed Topics:
Achievement standard 2.5 is internally assessed, with the optional 2.2 also being an internal.
Inter-class comparability / moderation will be achieved in the following ways:
- a rigid marking schedule will be formulated
- check marking between classes will be carried out to ensure and even standard of marking.
Other Assessment
Students will be expected to carry out on-going study throughout the year, learning for topic assessments which
relate to the units. Each major topic will be assessed with a knowledge test using the NCEA system of Achieve,
Merit and Excellence.
The school exam late in term three will give students practice in exam techniques as well as an opportunity to
understand the amount of effort required to achieve to the best of their ability.
Note: The results of all assessments will be significant if a derived grade (due to sickness, family
bereavement during exams) is sought.
Reassessment
There may be no reassessment opportunity for Internally Assessed Standards, depending on the particular
Standards requirements. It is therefore important that all students complete formative opportunities to the best of
their ability to get useful feedback prior to the summative assessments.
Records
Students will be supplied with a table giving assessment dates with space to keep an on going record of results.
Entering NCEA
Students will be expected to complete all work for this course. The number of Achievement Standards entered
will depend on the ability of the student. This decision will need to be made later in the year, in consultation with
care-givers and the classroom teacher.
Stationery
Students will be expected to purchase (at school) the Physics Workbook for NCEA Level 2 (Nelson) at a cost of
approximately $30.00. This contains the years notes and practice questions. A 1J8 exercise book is also of use.
Subject Progression:
Leads to the senior subject of level 3 Physics
Future Pathways:
Engineering, medicine, electrical, architecture and many more. Most of these
pathways have multiple career opportunities.
IMPORTANT – Year 13 Entry Requirement:
Passes in all of the external level 2 standards or with FL or HOD approval.

ACHIEVEMENT STANDARD OUTLINES
Physics 2.2 – AS 91169 - Credits 3 (Optional- for excellence endorsement)
Demonstrate understanding of physics relevant to a selected context
This achievement standard involves the understanding of physics relevant to a selected context.
Achievement Criteria
Achievement
Achievement with Merit
Achievement with Excellence
 Demonstrate understanding
of physics relevant to a
selected context.
 Demonstrate in-depth
understanding of physics
relevant to a selected context.
 Demonstrate comprehensive
understanding of physics
relevant to a selected context.
1
Demonstrate understanding involves providing characteristics of, or an account of the physics related to the
selected context.
Demonstrate in-depth understanding involves providing reasons as to how or why the physics applies to the
selected context.
Demonstrate comprehensive understanding involves linking ideas to integrate physics relevant to the
selected context, and involves elaborating, justifying, relating, evaluating, comparing and contrasting, or
analysing the physics underpinning the context.
2
The selected context must involve physics principles that are at curriculum Level 7. It may be
technological or biological.
