  • We encourage all parents to direct inquires during the school year via the following hierarchy so we can be most effective in responding to your needs:

    1. Our website features a special password-protected Parent Portal section (available to parents of enrolled students only) and provides access to our family directory, board packets, and handbooks.
    2. Calendars are available under the Calendar tab on the website. Our Master Calendar consists of all Petra dates and times (events, breaks, athletic competitions and events, etc.). This calendar is the only one we keep, so you can be confident in its accuracy (it’s also in real-time and smart phone-compatible to keep you up-to-date).
    3. INOW/Chalkable is our academic database that will be used exclusively to track grades, absences, and classroom specifics for your student(s). Parents will receive an email with a password from the Petra office during the first week of school for access to Chalkable. We will also conduct support workshops the first week after school starts for parents who want more training.
    4. All Petra Academy staff may be reached via email, most are at [firstname]@petraacademy.com. All teachers also have voicemail boxes. As a general guideline, please allow teachers 24 hours to respond to message.
    5. If you are unable to find what you need on the website, Chalkable, or by contacting your teacher, contact our office via email or by phone at (406) 582-8165, Monday-Friday from 8 a.m.-4 p.m. and we will be glad to help you.
  • Because of planning, staff meetings, and student oversight responsibilities, teachers are not available for meetings at the beginning of the school day. Parents needing to speak with teachers are encouraged to make an appointment via teacher email or voicemail to meet as teacher availability allows during the day or at 3:45 p.m. on Tuesdays through Fridays (teachers are in teacher training each Monday afternoon). Be sure to speak with your teacher(s) at Parent Orientation as to when and how to contact them outside of school hours, as teachers have families/relationships of their own beyond our school walls.

  • Lockers are provided as a courtesy to Secondary students to store personal items while on campus. Locker assignments will be available in the office the week before school. Students are encouraged (but not required) to provide their own combination lock to safeguard their belongings, but must register their combination with the Office Manager.

    All lockers are property of the school and subject to inspection. Students run the risk of losing locker privileges for a period of time or indefinitely if vandalized or unkempt. Gym lockers will also be assigned through the Office.

Thoughts on The Mission of Petra Academy

The Mission of Petra Academy

 Recognizing our need for God’s grace, Petra Academy strives to awaken love and wonder in our students by teaching to observe with humility, think with reason, and articulate with charity for the flourishing of humanity and the renown of Jesus the Christ.

Recognizing our need for God’s grace…

All of us are fallen; all of us need redeemed. This includes parents, and this includes our kids. Because of our fallenness, we see interactions through blurred lenses that affect our desires, words, thoughts, and motives.

The solution is not to look to ourselves for hope in some self-deluded self-esteem (which, by the way, is not a virtue); the problem – for us and for our students – is not that we have too little self-esteem, but that we have too much! Any hope of solution is to look outside ourselves to Christ.

The Apostle Paul tells us that Jesus is up to the challenge. Ephesians 2:8-9 reminds us that,

“…by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.”

We have been saved from death and hell, but we often forget verse 10:

“For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.”

Indeed, we have been saved from something, but we have also been saved for something.

To do any of this requires daily discipline, prayer, self-examination, repentance, and all of this requires grace to even desire it, let alone do it. Obedience to God’s word is what makes us fully human; we want and need to learn to love to obey. God’s law is the trellis that supports our love growing. Obedience equals freedom, for us and for our students, but it is God’s grace that makes any of it possible.


…Petra Academy strives to awaken love and wonder in our students…

Our students run the risk of going through life in a state of slumber. Many have been lulled to sleep by perhaps by a disengaged family life, a culture full of distractions, or perhaps a church that has sadly exchanged discipleship for entertainment.

Most of all, students – like all of us – are preoccupied with what they love, and what they love is not always good. James K.A. Smith, in his book, Desiring the Kingdom, sums up the quest of education in this question:

“What if education was primarily concerned with shaping our hopes and passions – our visions of ‘the good life’ – and not merely about the dissemination of data and information as inputs to our thinking? What if the primary work of education was the transforming of our imagination rather than the saturation of our intellect? And what if this had as much to do with our bodies as with our minds?…What if education wasn’t first and foremost about what we know, but about what we love?”

The good news is that our students have been lulled only to sleep, not to death (at least not yet). Like Sleeping Beauty, they need awakened to life through a kiss of love from beyond – engagement full of affection, wisdom, and understanding. Plato said that when we expose students to order, rhythm, and harmony, they will not only choose them, but also love them. As we expose them to size and scale, to precision and detail, to story and language, they will wonder, and wonder, said Plato, is the beginning of philosophy.

But philosophy to be true must be able to be lived, which is why we have teachers – those who have not only given their lives to learning and loving these philosophies, but are striving to live by them as well. As co-heirs of the promise given, as disciples of what has been taught, and as fellow human beings desperate for the same grace and redemption, our teachers have been awakened by Christ’s love and wonder, and strive to do the same in our students.


…by teaching them to observe with humility…

Teachers occupy a unique position of presence and relationship with their students. Our teachers make use of time-tested means to teach, and are held accountable by God and our school for what they teach. And yet, while they are under authority, they are also an authority in the lives of the students, and are worthy of respect from those they seek to teach as well as from those who have asked them to teach in loco parentis, that is, “in the place of (but not in place of) parents.”

Good teachers do not teach subjects; they teach students – not just the what, but the why and the how as well. Good teachers teach students to observe, doing so out of a particular framework or story of the world, which affects how they and their students interact. They teach students that identity comes not from within but from without, that if students will observe the world around them – through their senses, with their curiosity, in their context and environment – they will find their place in it with help from parents and teachers guiding them to such discovery.

Observation requires humility – to receive rather than to project meaning, to respond rather than to just react to an idea. To observe with humility is the result of a student recognizing that she does not know something, which Socrates calls the beginning of wisdom. To observe instead with arrogance is the completion of ignorance.


…think with reason…

While we are emotive beings, we also can be and are called to be rational ones. Perhaps a better word here is “reasonable” to define a thought or action that utilizes both emotion and rationale.

But more than just reasonable thought is our need for right thought; that is, for “obedient” thought, for surely there is thought that is “wrong” and “disobedient.” Thomas Aquinas makes this distinction when he challenges us to “love truth and hate falsehood” – you can’t do both. We are to love truth because all truth is God’s truth, but it requires effort and is not easy since we are fallen. Jiminy Cricket got it wrong. We should be careful to “always let your conscience be your guide,” because our conscience is fallen like everything else and needs redeemed.

To think with reason means to think God’s thoughts after him, to “set our minds on things above” as Colossians 3 reminds us. To recognize that words still carry weight and that that matters; to embrace that seeds of charity must be sown in order to grow souls that grow into logical emotive beings.


…articulate with charity…

Mechanics of expression are important, which is why we attempt to teach students to learn to submit to, practice, and emulate good forms. These good forms come by way of what might be thought of as an apprenticeship of revision, in which innate ability is considered, but not made more important than good preparation for expression.

Teachers promote a care for words, a right thinking based on obedient logic, and a gentle but firm rhetoric that causes students to blossom like the fruit of the Spirit of God’s word. Students are taught the importance of exegeting their audience as much as their content, understanding that the whole point of their presentation is for the persuasion and benefit of others rather than for themselves.

We implement the historic modes of persuasion – ethos (or character), logos (or content), and pathos (or appeal) – to affect emotion and experience. We study the craft of language to for the beautiful use of it, not for its own sake, but for the sake of influencing the embrace of Aristotle’s transcendentals of truth, goodness, and beauty. We practice and hone the ability to speak and awaken others by way of conviction, integrity, love, and good will for their audience, this leads to flourishing and any growth in Christ.


…for the flourishing of humanity…

Mankind flourishes when in proper relationship with the God who created him. Augustine speaks of this in The City of God when he speaks of the enculturation (or paideia) of students to become good citizens of the City of God within the culture of the City of Man. We believe that as we build good citizens for God’s Kingdom, they will be good citizens of our country. Rather than Republicans or Democrats, we are ultimately called to be Monarchists!

What are the results of a flourishing humanity?

Development of heart, mind, and body (illustration of facility)

A value for what is old, not because it is aged, but because it is timeless.

A value for what is new, not because it is novel, but because it is what God is doing.

A value for what is true, not because we care about who’s right, but because we’re called to care about what’s right.

A value for what is good, not because we are, but because we’ve been redeemed to be.

A value for what is beautiful, not because it is optional, but because it’s essential to human flourishing.


…the renown of Jesus the Christ.

“Renown” is the condition of being known or talked about by many people. We value what Jesus says because this – all of this – is for the renown of his name, not ours. The narrative story of creation, fall, redemption, consummation is the story of God’s desire from Genesis to Revelation that we would be his people and he would be our God. Jesus the Christ – the very Son of God – is the crux of this story, and as it has always been His story, we want our story at Petra Academy to reflect that.
