G ENERAL REQUIREMENTS FOR GWO B LADE R EPAIR
Upon completion of the GWO Blade Repair module (BR), participants will be aware of the risks and hazards encountered when working with blade inspection and repair within the wind industry. Furthermore, they will be able to control and mitigate those risks and hazards. The GWO blade repair training module will also equip participants with the knowledge, skills and confidence to appropriately respond in the event of a hazardous situation and to increase their safety through proper use of personal protective equipment, emergency equipment, procedures and safe craftsmanship.
Target group
Personnel who will be working in the wind industry specifically in relation to composite inspection and repair work. Personnel that perform job functions that have been risk assessed by their employer or their workplace duty holder as a function, where composite work training according to this standard may mitigate some of the identified hazards and risks.
Aims and strategic objectives
Training in accordance with this standard will enable participants to support and care for themselves and others working in the wind industry by possessing the knowledge and skills of composite inspection and repair work. Upon completion of the GWO Blade repair training course, participants will be able to work safely with composite materials while conducting inspection and basic blade repair procedures, thereby supporting an overall improvement of the safety for personnel with job functions focussing on composite repair work and inspection in the wind industry.
Guidance on delivering lesson elements
Section 10.4 gives the approximate duration of each of the lessons. The training provider may choose to deliver elements of the training according to other timetables, provided that the total duration is not reduced, and the duration of practical elements is not reduced in length. Theoretical elements should be delivered during the practical exercises whenever feasible.
Validity Period
The blade repair training is an enduring qualification and therefore a validity period does not apply to this training. This assumes that the participants are actively working with composite inspection and repair.

U NDERSTAND GWO L EARNING O BJECTIVES
Learning objectives
Learning objectives describe what the participant should know and be able to do when the training is completed. The learning objectives are based on the mitigating precautions analysed in the risk assessment, and are the foundation of the learning activities, the course contents and what the participant performance assessment must be based upon.
Coherence between the learning objectives, the learning activities and the assessment is essential. The purpose of this coherence is twofold. Firstly, this coherence ensures that learning activities are directly focused on reaching the learning objectives. Secondly, this coherence ensures that assessment of how well the learning objectives are met is done in close coherence with the abilities the participant has practiced during the learning activities and in a comparable environment to the participant ’ s subsequent work in the wind industry.
Enabling learning objectives are further sub-specifications of the learning objectives. Enabling objectives are what the instructor should be concentrating on when observing the participants ’ performance and development in action . Furthermore, evaluation should be focused on the enabling objectives as well as on the learning objectives. Ability is what is performed and presented during real-life exercises as well as in the real work situation and is the sum of experiences, knowledge, skills and attitudes. To be able to focus training on building up the necessary abilities, the learning objectives are described according to the taxonomy in the three domains: Knowledge, Skills and Ability.
Taxonomy
The GWO Taxonomy offers:
Guidance and support for training providers when designing both focused and assessable learning activities from the stated learning objectives. Guidance and inspiration for instructors when executing learning activities and when assessing the participants ’ learning outcome.
Digital advice when feasible.
Instructions and guidance for auditors when auditing in the pedagogical and didactic scope.
Learning objectives are presented in three taxonomic levels: Basic, Intermediate and Advanced level. The three levels in each domain are described as follows:
Global Wind Organisation www.globalwindsafety.org
13 / 135
GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V02
Knowledge
Skills
Ability
The participant understands a topic in a holistic view, where risks, advantages and disadvantages are considered, forming the background for reflected assessments or decisions for action.
The participant can experiment and refine his or her skills, as well as reflect and evaluate on the behaviour and reactions in relevant situations.
Can adapt and act responsibly in new ways, pay attention to the safety of fellow workers and propose development of safety procedures. Safety-awareness and responsibility are instinctive parts of ability. The participant can act independently, is able to identify connections and risks in work related situations and can take initiative and responsibility for feasible mitigating actions on the job. The participant can act independently in familiar work situations.
The participant can account for how things are done , or can explain how a piece of equipment or a tool is used .
The participant can test the applicability of the skill and distinguish between relevant and less relevant situations to apply the skill in. Basic cognitive and practical skills required to apply relevant instructions and procedures to solve routine problems using simple rules and tools.
The participant can describe a topic, name its constituent parts or simply refer to it. Basic knowledge is observed by a one- dimensional objective: “I can state a fact”.
The taxonomy levels in the learning objectives are defined by a reasonable number of precise and explained action-verbs. These action verbs are presented in a progression of increasing complexity - beginning on the basic level, where the participant can recognise or name a tool or a procedure, and ending at the advanced level, where the participant can take responsibility and even assist fellow workers on the work site. The taxonomy and the presentation of action verbs in the progressive order imply that the previous taxonomic competences are already achieved. Learning objectives in this standard are followed by an indication of the taxonomy level and domain in brackets e.g. (Skills, advanced level)
Summing up the learning objectives
A specific action verb indicates a taxonomic complexity level that calls for specific learning activities for the participant to reach the decided learning objectives.

2021-04-01_TS_BR_V02
During the learning activity, the participant shall practice doing what the action verb indicates.
In addition to this, the instructor’s evaluation in action, as well as the evaluation at the end of a module or a training, becomes transparent, when the participant’s ability to meet the learning objectives is assessed by comparing the partic ipant’s performance with the action verbs and contents of the learning objective.

A DMINISTRATION AND CERTIFICATION OF MODULES
Participant performance assessment
Participants will be assessed by means of direct observation and supplementary oral questions where appropriate (formative evaluation). Furthermore, the participants will be subjected to written phase tests after theory elements, and again after the close of the training course (summative evaluation). The written tests can consist of multiple choice or descriptive answer questions, and shall be set at the same taxonomy level as the objective that they are testing. There shall be at least one question for each lesson in the module.
The written tests shall be conducted in accordance with the following criteria:
(1) There shall be an instructor present in the room where written tests are being conducted for the entire duration of the written test
(2) The participants shall not communicate with each other during the test
(3) The participants shall not communicate with any persons via email, telephone, Skype (or similar) or social media during the test (4) The participants shall be allowed to use training material, handouts and their own notes during the test (5) Where a participant does not understand the meaning of a question or a multiple-choice option, the training staff shall be allowed to help the participant to understand the meaning of the question or the multiple-choice options. The training staff shall not give the participants the correct answers to any test questions
(6) There shall be a time limit of 1½ minutes per question
(7) The written test questions cannot be used during the training in such a way that the participants could recognise that they will be test questions.
(8) Each participant must answer at least 70% of written test questions correctly to pass the test.
If a participant does not reach the passing criteria in written or observational tests, the instructor shall discuss this with the participant to find out the reason for not reaching the passing criteria. If the reason is due to a misunderstanding of a question or due to language difficulties, then the instructor can mark a question as correct provided that the participants is able to demonstrate understanding of the lesson element being tested. This must be documented by the instructor and stored with the tests, control measures and evaluations for the course. Training providers shall have a documented procedure in place for dealing with participants not meeting the stated learning objectives. Throughout the entire GWO blade repair course, the instructor will use the participant assessment form (see Requirements for Training Providers) to evaluate the participants knowledge and skills, with a high focus on evaluating the participants ’ safety awareness and craftsmanship skills. The instructor shall keep a participant assessment form (or adaptation) for each participants until the completion / evaluation of the blade repair training module.
Global Wind Organisation www.globalwindsafety.org

GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V02
The participant assessment form (or adaptation) is a final evaluation tool for the instructors to assess participants during practical elements. It allows measurement of the number of violations regarding safety, competency or attitude. The participant assessment form shall be used as a progressive evaluation tool to discuss the performance of a participant to guide them to success. It also serves as supporting documentation if a participants passes or fails the module. If a participant fails to meet the demands of the blade repair training module, they can attend a new blade repair training in accordance with the contractual agreement when ordering the training course. The re-entry point is dictated by the stage where the participant left the course or where the instructor deems constructive. Training providers may adapt the participant assessment form to other media. Training providers must have a documented procedure in place for dealing with participants not meeting the stated learning outcomes.
