The public education landscape is enriched by having many options - neighborhood public schools, magnet schools, community schools, schools that focus on career and technical education, and even charter schools.

It's hard work to ensure that all schools are safe and welcoming places for all children. It means changing policies, practices and cultures; providing school support personnel; and funding programs like restorative justice - not simply resorting to excessive and often discriminatory discipline.

High-quality alternative educational settings should be available when students violate codes of conduct and need to be removed from the classroom while still maintaining access to instruction. And there must be social, health and psychological services to address students' needs.

There are essential elements for our public schools to fully develop the potential of both students and educators. They should be centers of community, where students, families and educators work together to support student success. They should foster collaboration.

Teachers need time to engage with colleagues - whether shadowing, mentoring, co-teaching or conferring. They need a voice in school decisions and to be trusted as professionals.

Learning should be engaging. Testing should not be the be all and end all. All students should have a broad curriculum that includes the arts and enrichment. Students should have opportunities to work in teams and engage in project-based learning. And student and family well-being should be front and center.

I've worked in public education for 30 years - as a teacher, a lawyer and union leader. I've visited hundreds of schools and districts. I've seen leaders from the classroom to the national stage who have been willing to set aside their differences and do the hard work that's necessary to create real, enduring change.

I can't imagine my life without books. My father was an electrical engineer, and my mother was a public school teacher. Books were an integral part of my childhood.

While books expand horizons by exposing us to worlds outside our own, children also need to see themselves, their experiences and their cultures reflected in books they read. Unfortunately, for too many children, this is not the norm.

Throughout my career as a lawyer, teacher and labor leader, books have remained my constant companion - stuffed into a briefcase, overflowing on my bedside table, stacked on my desk at work. Books have carried me to distant worlds, opened new doors and made me feel empathy, compassion, anger, fear, joy, acceptance - and everything in between.

I've made a lifetime commitment to the union movement and to public education.

For me, the labor movement and public education are linked as the essential building blocks to a strong middle class and a path to the American dream. It's why I went to Cornell's School of Industrial and Labor Relations as an undergrad and then to law school.

Beginning with the No Child Left Behind law and continuing today with Race to the Top, the federal emphasis on standardized assessments has become so excessive that it has modified state and district behavior in troubling ways.

Appropriate assessments are a crucial part of effectively educating students. But they only measure a narrow segment of what kids need to learn.

There is a recognition that Second Amendment rights, like First Amendment and other rights, come with responsibilities and limitations. There is no reason both sides of the gun debate can't support policies that both protect the right to legally own guns for sport and safety, and reduce the likelihood of mass fatalities.

Many schools desperately need caring professionals like guidance counselors and social workers to ensure students' emotional, social and educational needs are met. But proposals to arm teachers are irresponsible and dangerous. The role of educators is to teach and nurture our children, not to be armed guards.

When I taught, the way in which we got evaluated is what I used to call the drive-by evaluation. Somebody would come in for 20 minutes with a checklist, and that would be your evaluation. So it was clearly a snapshot.

Giving children a fair chance to achieve their dreams and reach their potential is everyone's responsibility.
