Mr. Cuomo called on the authority, which he effectively controls, to tell him what steps needed to be taken.

Virus admissions at state’s hospitals have fallen 70 percent.

The number of coronavirus patients newly admitted to hospitals in New York State has fallen more than 70 percent since the outbreak’s peak this month, according to statistics that Mr. Cuomo cited on Tuesday.

The number reported Tuesday was below 1,000 for the first time in over a month, down from more than 3,000 reported on April 4 — further evidence that the outbreak was waning.

Deaths from the virus remained flat — 335 more people died on Tuesday, Mr. Cuomo said, an almost identical figure to the 337 deaths reported on Monday.

New York City changes the grading system for public schools.

Six weeks into a profoundly disrupted semester, Mayor Bill de Blasio on Tuesday announced a new grading system effective through the end of the school year for the city’s 1.1 million students.

Students across the system will not receive failing grades, the mayor said as he laid out the policies:

Elementary school: Students in kindergarten through fifth grade will be graded either as “meets standards” or “needs improvement.” Because summer school plans are still being worked out, it is not yet clear whether children will be held back if they fall behind academically.

Middle school: Students will be assessed using the same marks but can also receive a grade of “course in progress,” if teachers need more information to determine whether a student has mastered a class’s coursework. Those students will get priority for remedial help during the summer and fall.
