Education and Training in the Care and Use of Laboratory Animals: A Guide for Developing Institutional Programs 1 Core Module INTRODUCTION The core module is recommended for all personnel involved both directly and peripherally with animals used in research, education, and testing. It has been designed as an introduction that will enable participants to follow through on subjects that relate to their interests. A lecture/seminar format is recommended for presenting most of the core material, as this format is well suited for communicating the institutional mandate, is appropriate for groups of any size, and makes the most efficient use of resources. If the number of people requiring training within an institution is very small, consideration might be given to participation in a program offered by a larger institution or to the pooling of resources by several small institutions. A session might include several speakers, each of whom is responsible for an assigned topic. Prepackaged video or slide materials can be used effectively for portions of the presentation, particularly when human resources are limited. Handouts are also useful adjuncts to the presentation. Two of the appendixes to this guide are recommended as handouts in the outline below. It is also recommended that written institutional policies applicable to the topics be distributed. Other handouts should be developed to fit the needs of the speakers and the participants. The topics contained in the outline below are those considered by the EPLAS committee to be essential elements of an introductory education program on the care and use of laboratory animals. The recommended presentation time is 3 to 4 hours. In this amount of time, it will not be possible to deal with the topics in depth; however, it is important to address the legal and ethical aspects of every topic. Although the committee has estimated a presentation time for each topic in the outline, the actual time will depend

Education and Training in the Care and Use of Laboratory Animals: A Guide for Developing Institutional Programs on the emphasis to be placed on each topic and depth of coverage required to fulfill the needs of the institution and the participants. In addition, significant time should be allotted for participants to ask questions and discuss the issues. The recommended content of each topic below is cross-referenced to the expanded outlines contained in Part III, Chapters 1–9, of this guide by the numbers in parentheses following each sentence. The number preceding the decimal point indicates the chapter, and the number(s) following the decimal point indicates the place within the chapter that the information appears. Thus, 1.1 indicates the first entry in chapter 1 of part III, and 1.2.1 indicates the first subentry under the second entry in chapter 1.

Education and Training in the Care and Use of Laboratory Animals: A Guide for Developing Institutional Programs 2 Species-Specific Module INTRODUCTION This module should be provided for all people who will be in direct contact with animals. Only one species or closely related species should be covered in a particular session. The emphasis on each topic will vary according to the needs of the participants and the species of animal considered. The cognitive aspects of the species-specific module can be presented in the form of independent-study materials; therefore, estimated presentation times are not included. Demonstrations and visual aids should not be substituted for the hands-on experience needed by participants to develop their skills, although they can be helpful in introducing a laboratory exercise. Associated skill-building sessions should be done in small groups or in individual laboratory settings. As in the core module, the recommended content of each topic below is cross-referenced to the expanded outlines contained in Part III. The material will be found primarily in Chapter 10 (Species-Specific Overview), with additional material taken from Chapters 8 (Euthanasia) and 9 (Husbandry, Care, and Importance of the Environment).
