Outcomes and evidence requirements Outcome 1 Collect scion wood from a minimum of three species and/or cultivars.
Evidence requirements 1.1 Scion wood is marked when its characteristics are most obvious, or sourced from reputable supplier.
1.2 Scion wood selected and cut is appropriate for the species and/or cultivar, and in accordance with workplace procedures.
Range from marked plants or reputable supplier, pest and disease free, suitable diameter and growth stage, exposed to the sun, labelled with species and/or cultivar name.
1.3 Scion wood is bundled, and stored until needed, in conditions that maintain viability.
Outcome 2 Graft plants.
Evidence requirements 2.1 The time selected for grafting is appropriate for plant species and/or cultivar, and the techniques used.
2.2 Root stock plants are prepared for grafting in the field or in the greenhouse as appropriate for plant species.
2.3 Plants are root grafted or top grafted in accordance with workplace procedures.
Range two of – whip, whip and tongue, cleft, machine, side.
2.4 Each graft is completed in a manner that promotes success.
Range compatibility, sufficient buds per scion, scions right way up, smooth cuts, cambium layers matching, firmly tied or secured, cut surfaces weatherproof.
Outcome 3 Bud plants.
Evidence requirements 3.1 The time selected for budding is appropriate for plant species and/or cultivar, and the technique used.
3.2 Root stock plants are prepared for budding as appropriate for plant species.
3.3 Plants are budded in accordance with workplace procedures.
Range one of – T-bud or inverted T-bud, chip bud.
3.4 Each bud is completed in a manner that promotes success.
Range compatibility, buds right way up, smooth cuts, cambium layers matching, firmly secured in place.
Outcome 4 Care for plants after grafting or budding.
Evidence requirements 4.1 For grafted plants held indoors, the environment is maintained to encourage callusing, graft union formation, and plant growth.
4.2 Field grafted plants are maintained in accordance with workplace procedures to maximise growth, and to prevent competition from pests, diseases, and weeds.
4.3 Tapes, patches, or other holding devices are removed where necessary after the bud or graft has taken in order to prevent restriction of plant stem scion growth.
4.4 Budded plants are cut back to the bud, and the cut surface is treated in accordance with workplace procedures.
4.5 Scion growth is supported if necessary, and competing root stock growths are removed, in accordance with workplace procedures.
Outcome 5 Keep records of propagation by budding and grafting.
Evidence requirements 5.1 Propagated plant material is labelled and identified in accordance with workplace procedures.
Range may include plant species or cultivar name, date, operators.
5.2 Records of plants propagated are kept in accordance with workplace procedures.
Range may include species and/or cultivar name, source of scion material, date scion material collected, date scion material used, budding or grafting technique, heading back of rootstock.

This CMR can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.
Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR).
