As countries consider how to reopen schools safely in the context of COVID-19 (coronavirus), one key question is how to assess students' learning to support learning recovery. The expected magnitude of learning losses, particularly among students with the highest needs, makes it essential for key stakeholders in the education process - policymakers, teachers, school principals, students, and their parents - to determine where students are in their learning trajectory relative to what had been expected prior to the pandemic, so they can adjust instruction and allocate resources accordingly. To collect this information, stakeholders can rely on student learning assessment, which is an essential feedback mechanism in the education system. This note provides key steps that countries with different availability of resources should consider in developing their plans for learning assessment activities to support learning recovery in the context of school reopening. Throughout this note, assessment of student learning is defined as gathering and evaluating information on what students know, understand, and can do to make informed decisions about the next steps in the educational process. In addition, some considerations and country examples for the implementation of high-stakes examinations are discussed. This note concludes with examples of learning assessment activities that countries around the world are planning or implementing during the COVID-19 pandemic. Likewise, this note highlights important lessons that can support resilience to future emergencies and crises.

The covid-19 pandemic is increasingly a concern for developing countries. Using a new database on COVID-19 trade flows and policies, this note looks at the role of trade and trade policy to address the looming health crisis in developing countries with highest numbers of recorded cases. It shows that export restrictions by leading producers could cause significant disruption in supplies and contribute to price increases. Tariffs and other restrictions to imports further impair the flow of critical products to developing countries.

Faced with COVID-19 (Coronavirus), countries are taking drastic action based on little information. Two tests can help governments shorten and soften economically costly suppression measures while still containing the novel coronavirus (COVID-19) pandemic. The first-a PCR assay-identifies people currently infected by testing for the presence of live virus in the subject. The second-an antibody test-identifies those rendered immune after being infected by searching for COVID-19-specific antibodies. The first test can help contain the disease because it facilitates the identification of infected persons, the tracing of their contacts, and isolation in the very early stages of an epidemic-or after a period of suppression, in case of a resurgent epidemic. The second can help us assess the extent of immunity in the general population or subgroups, to finetune social isolation and to manage health care resources. Wide application of the two tests could transform the battle against COVID-19 (Coronavirus), but implementing either on a large scale in developing countries presents challenges. The first test is generally available, but needs to be processed in adequately equipped laboratories with trained staff. The second test is easy to perform and can be processed quickly on the spot, but at this stage it is produced and available only on a limited basis in a few countries. This policy brief reviews the use of both tests, suggests strategies to target their use, and discusses the benefits and costs of such strategies. If PCR assay testing, together with tracing and isolation, helps reduce the duration of suppression measures by two weeks, and antibody testing allows one-fifth of the immune return to work early, the gain could be about 2 percent of national income, or about
