Book excerpt: Use this book to prepare for the ISTQB® Certified Tester Foundation Level Performance Testing exam. The book has been designed to follow the ISTQB syllabus, covering all of the syllabus learning objectives, with additional reference material extending beyond the syllabus. The book covers an overall methodology for managing and conducting performance testing. Performance testing has often been considered a black art. In many organizations, perhaps an individual or a small group of technical staff or contractors is given the task of "load testing" an extended system, network, or application. Performance testing is like any other form of testing. It follows a defined test process that is similar to other test types. It utilizes a disciplined approach to the definition of requirements and user stories, the creation of test conditions, test cases, and test procedures. It establishes measurable goals against which the success or failure of the testing can be judged. It also requires (and this cannot be stressed highly enough) a definition and recognition of performance test failures. Readers will gain the knowledge with both content and practice questions to prepare them for the ISQTB Performance Testing exam. The book covers the performance test types, the performance testing methodology, and the steps to plan, create, and execute performance tests and analyze the results. You will: Understand the basic concepts of performance efficiency and performance testing Define performance risks, goals, and requirements to meet stakeholder needs and expectations Understand performance metrics and how to collect them Develop a performance test plan for achieving stated goals and requirements Conceptually design, implement, and execute basic performance tests Analyze the results of a performance test and communicate the implications to stakeholders Explain the process, rationale, results, and implications of performance testing to stakeholders Understand the categories and uses for performance tools and criteria for their selection Determine how performance testing activities align with the software life cycle .
Download or read book Incentives and Test Based Accountability in Education written by National Research Council and published by National Academies Press. This book was released on 2011-10-18 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there have been increasing efforts to use accountability systems based on large-scale tests of students as a mechanism for improving student achievement. The federal No Child Left Behind Act (NCLB) is a prominent example of such an effort, but it is only the continuation of a steady trend toward greater test-based accountability in education that has been going on for decades. Over time, such accountability systems included ever-stronger incentives to motivate school administrators, teachers, and students to perform better. Incentives and Test-Based Accountability in Education reviews and synthesizes relevant research from economics, psychology, education, and related fields about how incentives work in educational accountability systems. The book helps identify circumstances in which test-based incentives may have a positive or a negative impact on student learning and offers recommendations for how to improve current test-based accountability policies. The most important directions for further research are also highlighted. For the first time, research and theory on incentives from the fields of economics, psychology, and educational measurement have all been pulled together and synthesized. Incentives and Test-Based Accountability in Education will inform people about the motivation of educators and students and inform policy discussions about NCLB and state accountability systems. Education researchers, K-12 school administrators and teachers, as well as graduate students studying education policy and educational measurement will use this book to learn more about the motivation of educators and students. Education policy makers at all levels of government will rely on this book to inform policy discussions about NCLB and state accountability systems.

Download or read book The National Fuel End use Efficiency Field Test Energy Savings and Performance of an Improved Energy Conservation Measure Selection Technique written by M.P. Ternes and published by . This book was released on 1991 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of an advanced residential energy conservation measure (ECM) selection technique was tested in Buffalo, New York, to verify the energy savings and program improvements achieved from use of the technique in conservation programs and provide input into determining whether utility investments in residential gas end-use conservation are cost effective. The technique analyzes a house to identify all ECMs that are cost effective in the building envelope, space-heating system, and water-heating system. The benefit-to-cost ratio (BCR) for each ECM is determined and cost-effective ECMs (BCR> 1.0) are selected once interactions between ECMs are taken into account. Eighty-nine houses with the following characteristics were monitored for the duration of the field test: occupants were low-income, houses were single-family detached houses but not mobile homes, and primary space- and water-heating systems were gas-fired. Forty-five houses received a mix of ECMs as selected by the measure selection technique (audit houses) and 44 served as a control group. Pre-weatherization data were collected from January to April 1988 and post-weatherization data were collected from December 1988 to April 1989. Space- and waterheating gas consumption and indoor temperature were monitored weekly during the two winters. A house energy consumption model and regression analysis were employed to normalize the space-heating energy savings to average outdoor temperature conditions and a 68 F indoor temperature. Space and water-heating energy savings for the audit houses were adjusted by the savings for the control houses. The average savings of 257 therms/year for the audit houses was 17% of the average pre-weatherization house gas consumption and 78% of that predicted. Average space-heating energy savings was 252 therms/year (25% of pre-weatherization space-heating energy consumption and 85% of the predicted value) and average water-heating savings was 5 therms/year (2% of pre-weatherization water-heating energy consumption and 17% of predicted). The overall BCR for the ECMs was 1.24 using the same assumptions followed in the selection technique: no administration cost, residential fuel costs, real discount rate of 0.05, and no fuel escalation. A weatherization program would be cost effective at an administration cost less than $335/house. On average, the indoor temperature increased in the audit houses by 0.5 F following weatherization and decreased in the control houses by 0.1 F. The following conclusions regarding the measure selection technique were drawn from the study: (1) a significant cost-effective level of energy savings resulted, (2) space-heating energy savings and total installation costs were predicted with reasonable accuracy, indicating that the technique's recommendations are justified, (3) effectiveness improved from earlier versions and can continue to be improved, and (4) a wider variety of ECMs were installed compared to most weatherization programs. An additional conclusion of the study was that a significant indoor temperature take-back effect had not occurred.

Download or read book Psychological Testing in the Service of Disability Determination written by Institute of Medicine and published by National Academies Press. This book was released on 2015-06-29 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Social Security Administration (SSA) administers two disability programs: Social Security Disability Insurance (SSDI), for disabled individuals, and their dependent family members, who have worked and contributed to the Social Security trust funds, and Supplemental Security Income (SSSI), which is a means-tested program based on income and financial assets for adults aged 65 years or older and disabled adults and children. Both programs require that claimants have a disability and meet specific medical criteria in order to qualify for benefits. SSA establishes the presence of a medically-determined impairment in individuals with mental disorders other than intellectual disability through the use of standard diagnostic criteria, which include symptoms and signs. These impairments are established largely on reports of signs and symptoms of impairment and functional limitation. Psychological Testing in the Service of Disability Determination considers the use of psychological tests in evaluating disability claims submitted to the SSA. This report critically reviews selected psychological tests, including symptom validity tests, that could contribute to SSA disability determinations. The report discusses the possible uses of such tests and their contribution to disability determinations. Psychological Testing in the Service of Disability Determination discusses testing norms, qualifications for administration of tests, administration of tests, and reporting results. The recommendations of this report will help SSA improve the consistency and accuracy of disability determination in certain cases.
