评估被定义为进行比较并评估实现既定目标的进展的过程。目标,和自基线期或自上次评估以来的目标。评估的目的是了解项目对社区的影响，并确定项目是否实现了目标。规划和评估是交织在一起的。为了实现准确的评估，需要1）适当的指标和2）定期收集数据。在不同的评估类型和模型中，在决定项目的可行性之前，初步评估或需求评估是必不可少的。这可能是对社区的调查，所谓的可行性研究或形成性评估。在这个阶段，收集基线数据也很重要。监测和定期评估意味着在项目进展期间通过保持准确的每日记录和每周或每月举行会议来收集数据。每6-12个月进行一次定期评估，以评估问题和成就。监测要求每周或每月报告服务统计数据(例如，新接受者和受训人员的数量，避孕药具分布，和购买的材料)。在项目结束后立即进行最终评估。它涉及最终数据结果与基线数据的比较。它可以确定导致缺点的因素，并提出纠正这些缺点的方法。内部评估是在内部进行的，而外部评估则由独立的外部评估员进行。测量工具用于定期测量性能，使用指标(卫生政策指标，社会和经济指标，提供健康的指标，和健康状况指标)。
Evaluation is defined as a process by which comparisons are made and progress is assessed towards accomplishment of stated goals, objectives, and targets since the baseline period or since the last evaluation. The purpose of evaluation is to find out about the project\'s impact on the community as well as to determine whether or not the project achieved its objectives. Planning and evaluation are intertwined. For the achievement of an accurate evaluation there is need for 1) adequate indicators and 2) regular collection of data. Among different types and models of evaluation, preliminary evaluation or needs assessment is essential before deciding on the viability of the project. This could be a survey of the community, a so-called feasibility study or formative evaluation. At this stage it is also important to collect baseline data. Monitoring and periodic evaluations mean collecting data while the project progresses by means of keeping accurate daily records and holding weekly or monthly meetings. Period evaluations are carried out every 6-12 months to assess problems and achievements. Monitoring requires the reporting of service statistics weekly or monthly (e.g., the numbers of new acceptors and of trainees, contraceptive distribution, and materials purchased). Final evaluation is done right after the project has concluded. It involves the comparison of final data results with the baseline data. It can identify the factors which have led to shortcomings and suggest ways to redress them. Internal evaluations are performed in-house, while external evaluations are carried out by an independent outside evaluator. Measurement tools are used for the measurement of performance at regular intervals, employing indicators (health policy indicators, social and economic indicators, indicators of provision of health, and health status indicators).
