拜登政府的一名高级顾问周四表示，疾病控制和预防中心将于周五发布重新开放学校的公共卫生指南。

新冠肺炎响应组织的高级顾问安迪·斯拉维特(Andy Slavitt)周四在MSNBC表示，疾控中心将“推出他们的运营计划，为学区和当地社区提供他们需要的指导，以开始并积极开展这项工作。”

“关于是否在这里开办学校没有争论，有一个关于如何开办的争论，”他说。

问题是拜登政府会走多远。大流行已经将近一年了，但是对于什么时候开办学校是安全的，联邦政府仍然没有一个明确的标准。在新冠肺炎，只有学校运营指南，包括手卫生和戴口罩等缓解策略的考虑。

疾控中心即将提出的建议正值拜登政府重新开放学校的计划受到一些审查之际。

起初，这似乎是一个大胆的计划:目标是在100天内重新开放大多数学校。但本周，当白宫新闻秘书珍·普萨基澄清政府所说的“开放”是什么意思时，这种新奇感很快受到了质疑。

普萨基说，这个目标意味着确保50%以上的八年级学校每周至少有一天提供面对面的学习。

“绝对可悲！”发微博共和党众议员弗吉尼亚·福克斯对此作出回应。

“学生们应该得到的不仅仅是这种安全返回教室的微薄方法，”她补充道。

R-Mo代表Vicky Hartzler。,发微博:“我们只有51%的学校一周只开学一天，这不是‘成功’我们应该努力让我们所有的孩子安全地回到全职的、面对面的学习中。"

特朗普政府要求学校重新开放，但没有向学校和教师提供何时重新开放是安全的明确指导。特朗普政府的教育部也从未从学校收集过关于关闭或最佳做法的数据——这些信息可能有助于通知当地官员，他们正在努力决定何时开放或关闭教室。

普萨基周三为政府的立场辩护，告诉记者:“总统的目标是所有学校重新开放，保持开放，每周开放五天，让孩子们学习。这就是我们关注的焦点。这简直就是100天的目标。”

“这也是我们希望全国大多数学校都去的地方，但现在还没有，我们想从那里开始建设，”她说。

但根据至少一项数据服务，大多数学校已经开放。

布尔比奥，据其网站称“，审核代表美国3000个县的跨地区的一套全面的中小学学习计划，周一报道大约64%的K-12学生就读的学校提供某种形式的面对面学习，包括混合和传统学习环境。

周四，Psaki说，部分挑战是“数据并不太好，因为它涉及到开放或不开放的学校，混合学习是如何影响孩子的。”

上周，教育部宣布开始收集学校重新开放的数据，以深入了解“全国开放全日制面对面教学、开放在线和面对面教学或完全远程教学的学校比例。”

“我们期待听到他们清晰的、基于科学的安全开放学校并保持开放的指导方针，”普萨基说。“这些指导方针将成为我们的健康和医疗专家、疾病预防控制中心令人难以置信的领导、我们未来的教育部长[米格尔]卡多纳将如何与全国各地的学区合作安全重新开放的基础。这就是我们的重点。但数据和缺乏数据或有效数据实际上是问题的一部分，”她说。

CDC to release guidance on reopening schools as Biden's plan comes under scrutiny

Public health guidance for reopening schools will be released Friday by the Centers for Disease Control and Prevention, a top adviser in the Biden administration said Thursday.

Andy Slavitt, a senior adviser for the COVID-19 response, said on MSNBC Thursday that the CDC will “roll out their operating plan to give school districts, local communities the guidance they need to begin to do that and do that aggressively.”

“There's no debate over whether to open schools here, there's a debate on how,” he said.

In question is how far the Biden administration will go. Almost a year into the pandemic, there still has not been a clear federal standard on when it is safe to open a school. There has only been guidance for operating schools during COVID-19, including considerations for mitigation strategies like hand hygiene and wearing masks.

The upcoming recommendations from the CDC come as the Biden administration’s plan to reopen schools is under some scrutiny.

It initially appeared to be a bold plan: a goal to reopen the majority of schools in 100 days. But the novelty was swiftly called into question this week when White House Press Secretary Jen Psaki clarified what the administration meant by “open.”

Psaki said that goal meant ensuring over 50% of K-8 schools offered in-person learning at least one day a week.

“Absolutely pathetic!” tweeted Rep. Virginia Foxx, R-N.C., in response.

“Students deserve more than this meager approach to returning safely to their classrooms,” she added.

Rep. Vicky Hartzler, R-Mo., tweeted: “Having only 51% of our schools reopen for as little as one day a week is not a ‘success.’ We should be working to safely get all of our children back to full-time, in-person learning.”

The Trump administration had demanded that schools reopen but without clear guidance to schools and teachers on when it would be safe to do so. The Trump administration’s Education Department also never collected data from schools on closures or best practices -- information that could have been useful in informing local officials struggling to make decisions on when to open or close classrooms.

Psaki defended the administration's position on Wednesday, telling reporters: “The President's objectives is for all schools to reopen, to stay open, to be open five days a week, for kids to be learning. That's what our focus is on. This is simply a goal for 100 days.”

“That's, again, the bar of where we'd like the majority of schools across the country to be, which they're not at this point in time, and we want to build from there,” she said.

But according to at least one data service, the majority of schools are already open.

Burbio, which, according to its website, "audits a comprehensive set K-12 learning plans across districts representing 3,000 US counties in the US, reported on Monday that approximately 64% of K-12 students are attending a school with some form of in-person learning available, including hybrid and traditional learning environments.

On Thursday, Psaki said part of the challenge is "that the data is not great as it relates to schools that are open or not open, how hybrid learning is impacting kids."

Last week, the Education Department announced it was beginning to collect data on school reopenings to get insights into things like the “share of the nation’s schools that are open with full-time in-person instruction, open with online and in-person instruction, or fully remote.”

"We look forward to hearing their clear, science-based guidelines for opening schools safely and keeping them open," Psaki said. "These guidelines are going to be the basis for how our health and medical experts, the incredible leadership at the CDC, our future Secretary of Education [Miguel] Cardona will work with school districts around the country to safely reopen. And that's where our focus will be. But the data and the lack of data or effective data is actually part of the problem" she said.
