Certification in the context of "Diving certification"

Non-formal learning includes various structured learning situations which do not either have the level of curriculum, institutionalization, accreditation or certification associated with 'formal learning', but have more structure than that associated with 'informal learning', which typically take place naturally and spontaneously as part of other activities. These form the three styles of learning recognised and supported by the OECD.

Examples of non-formal learning include swimming sessions for toddlers, community-based sports programs, and programs developed by organisations such as the Boy Scouts, the Girl Guides, community or non-credit adult education courses, sports or fitness programs, professional conference style seminars, and continuing professional development. The learner's objectives may be to increase skills and knowledge, as well as to experience the emotional rewards associated with increased love for a subject or increased passion for learning.

The Blue Flag is a certification by the Foundation for Environmental Education (FEE) that a beach, marina, or sustainable boating tourism operator meets its standards. The Blue Flag is a trademark owned by FEE, which is a not-for-profit, non-governmental organisation consisting of more than 100 organisations spreading 81 countries. As of 2025, Spain is the country with the most Blue Flag beaches in the world, with 642 Blue Flags and 749 awards in total.

FEE's Blue Flag criteria include standards for quality, safety, environmental education and information, the provision of services, and general environmental management. The Blue Flag is hence sought as an indication of high environmental and quality standards.

An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts.

Phytosanitary certification verifies phytosanitary worthiness (plant health). These certificates are used to attest that consignments meet phytosanitary import requirements and are undertaken by a National Plant Protection Organization (NPPO). Under the Agreement on the Application of Sanitary and Phytosanitary Measures and ISPM, a certificate for export or for re-export can be issued only by a public officer who is technically qualified and duly authorized by an NPPO.

A phytosanitary certificate for export is usually issued by the NPPO of the country where the plants, plant products, or regulated articles were grown or processed. Phytosanitary certificates are issued to indicate that consignments of plants, plant products or other regulated articles meet specified phytosanitary import requirements and are in conformity with the certifying statement of the appropriate model certificate. Phytosanitary certificates should only be issued for this purpose.

Digital Living Network Alliance (DLNA) is a set of interoperability standards for sharing home digital media among multimedia devices. It allows users to share or stream stored media files to various certified devices on the same network like PCs, smartphones, TV sets, game consoles, stereo systems, and NASs. DLNA incorporates several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, wired and wireless networking standards, and widely used digital media formats. Many routers and network attached storage (NAS) devices have built-in DLNA support, as well as software applications like Windows Media Player.

DLNA was created by Sony and Intel and the consortium soon included various PC and consumer electronics companies, publishing its first set of guidelines in June 2004. The Digital Living Network Alliance developed and promoted it under the auspices of a certification standard, with a claimed membership of "more than 200 companies" before dissolving in 2017. By September 2014 over 25,000 device models had obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices.

Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness. The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak. Food safety includes a number of routines that should be followed to avoid potential health hazards. In this way, food safety often overlaps with food defense to prevent harm to consumers. The tracks within this line of thought are safety between industry and the market and then between the market and the consumer. In considering industry-to-market practices, food safety considerations include the origins of food including the practices relating to food labeling, food hygiene, food additives and pesticide residues, as well as policies on biotechnology and food and guidelines for the management of governmental import and export inspection and certification systems for foods. In considering market-to-consumer practices, the usual thought is that food ought to be safe in the market and the concern is safe delivery and preparation of the food for the consumer. Food safety, nutrition and food security are closely related. Unhealthy food creates a cycle of disease and malnutrition that affects infants and adults as well.

Food can transmit pathogens, which can result in the illness or death of the person or other animals. The main types of pathogens are bacteria, viruses, parasites, and fungus. The WHO Foodborne Disease Epidemiology Reference Group conducted the only study that solely and comprehensively focused on the global health burden of foodborne diseases. This study, which involved the work of over 60 experts for a decade, is the most comprehensive guide to the health burden of foodborne diseases. The first part of the study revealed that 31 foodborne hazards considered priority accounted for roughly 420,000 deaths in LMIC and posed a burden of about 33 million disability adjusted life years in 2010. Food can also serve as a growth and reproductive medium for pathogens. In developed countries there are intricate standards for food preparation, whereas in lesser developed countries there are fewer standards and less enforcement of those standards. In the US, 5,000 deaths per year were related to foodborne pathogens in 1999. Another main issue is simply the availability of adequate safe water, which is usually a critical item in the spreading of diseases. Food poisoning cannot be completely avoided due to the number of persons involved in the supply chain, as well as the fact that pathogens can be introduced into foods no matter how many precautions are taken.
